Get the NCERT Solutions for CBSE Class 8 Maths Chapter 2 Linear Equations in One Variable on TopperLearning. Learn to solve equations with variables on both sides. Understand how to solve equations with numbers on one side or linear expressions on the other side.

- An equation is a statement of equality of two algebraic expressions involving one or more unknown quantities.
- An equation involving only a linear polynomial is called a linear equation.

For example: - Any value of the variable which makes the equation a true statement is called the solution or root of the equation.

For example: - 2 is root of the equation 3x - 2 = -8. - Any term of an equation may be taken to the other side with its sign changed, without affecting the equality. This process is called transposition.
- Without changing the equality, we may

i. add the same quantity to both sides of the equation.

ii. subtract the same quantity from both sides of the equation.

iii. multiply both sides of the equation by the same non-zero quantity.

iv. divide both sides of the equation by the same non-zero quantity. - If , then q (ax + b) = p (cx + d)

This process is called cross multiplication.

Cube number

Cube of a number is obtained when it is multiplied by itself thrice.

If ‘a’ is a number, then the cube of ‘a’ is a3 = a × a × a.

A natural number n is a perfect cube if n can be expressed as m3, for some natural number m. The numbers 1, 8, 27 are perfect cubes.

To find whether a number is a perfect cube or not:

Express the number as the product of prime factors.

If each factor appears three times in the prime factorization, the number is a perfect cube.

If there are one or more factor(s) which do not appear 3 (or multiples of 3) times, the number is a non-perfect cube.

64 = 4 × 4 × 4, is a perfect cube. 72 = 2 × 2 × 2 × 3 × 3 = 22 × 32, is not a perfect cube.

What are constant and variable?

Constant is a symbol that takes fixed numerical value which is represented by letters.

Variable is a symbol that takes various numerical values which is represented by letters.

Algebraic Expression

A combination of constants and variables connected by the operators +, -, Χ and is known as an algebraic expression.

Example: 15 x 2 – 9x + 4xy is an algebraic expression.

What is an identity?

An identity is an equality, which is true for all values of variables in it.

On the other hand, an equation is true only for certain values of the variables in it. An equation is not an identity.

Some standard and important identities:

(a + b)^{2} = a^{2}+2ab+b^{2}

(a – b)^{2} = a^{2} – 2ab + b^{2}

(a + b)(a – b) = a^{2} – b^{2}

(x + a)(x + b) = x^{2} + (a + b)x + ab

Use of algebraic identities

The algebraic identities are useful in carrying out the square and products of algebraic expressions.

They can also be used as an alternative method to calculate product of numbers.

NCERT Solutions for CBSE Class 8 Mathematics Chapter 11 Mensuration

How to calculate the perimeter of a square or a rectangle? How to compute the area of a pentagon? Learn by practicing the NCERT Solutions for CBSE Class 8 Maths Chapter 11 Mensuration with TopperLearning. When you practise the expert solutions, you will understand the ways to apply the techniques to find the area of real objects.

Area of a polygon (or field) can be calculated by suitably dividing it into triangle, rectangle, trapezium etc. Surface area of a solid is the sum of the areas of all its faces. Amount of region occupied by a solid is called its volume.

For a cuboid of length l, breadth b and height h, we have:

Volume of cuboid = (l b h) cubic units

Total surface area of cuboid = (lb + bh + lh) sq units

Lateral surface area of cuboid = {2(l + b) h] sq units

Diagonal of cuboid = units

Unit conversion:

1 cm^{3} = 1 mL

1 L = 1000 cm^{3}

1 m^{3} = 106 cm^{3} = 1000 L

- Large numbers can be written in shorter form using exponents.

For example: 1000 = 103

Here, 103 is called the exponential form of 1000.

10the number that is being multiplied) is called the base.

3 (number of times the same number is multiplied by itself) is called the power (or index or exponent) - As the exponent increases by 1 the value becomes ten times the previous value.
- As the exponent decreases by 1 the value becomes the previous value.
- For any non-zero integer ‘a’, , where m is a natural number.
- For a and b non-zero rational numbers, then
- Laws of exponents: If 'a' and 'b' are rational numbers different from zero and if x, y are positive integers, then

- ax ay = ax+y
- ax ay = ax – y
- (ax)y = axy
- (ab)x = ax bx
- a0 = 1
- (-1)odd number = -1

(-1) even number = 1

NCERT Solutions for CBSE Class 8 Mathematics Chapter 13 Direct and Inverse Proportions

Revise concepts from the syllabus using TopperLearning’s NCERT Solutions for CBSE Class 8 Mathematics Chapter 13 Direct and Indirect Proportions. Learn to apply the concept of direct proportion to find answers in real-life scenarios such as whether a pigment and its base are in the right proportion.

Two quantities x and y are said to be in direct proportion if whenever the value of x increases (or decreases), then the value of y increases (or decreases) in such a way that the ratio remains constant.

Example: Work done is directly proportional to the number of men working on it.

Two quantities x and y are said to be indirect proportion if whenever the value of x increases (or decreases), then the value of y decreases (or increases) in such a way that xy remains constant.

Example: The time taken by any vehicle in covering a certain distance is inversely proportional to the speed of the car.

Watch a problem solving video on indirect proportion.

Map is a miniature representation of a large regions. Hence we can say that scale of a map is based on the concept of direct variation.

Suppose A can finish a piece of work in n days. Then, work done by A in 1 day =

When a person A completes part of the work in one day, then A will take n days to complete the work.

In a cistern there are two pipes. The inlet is the pipe that fills the cistern and the outlet is the pipe that empties the cistern.

When an inlet fills the cistern in ‘n’ hours, then it will fill up part of the cistern in one hour.

When an outlet empties the cistern in ‘n’ hours, then it will empty out part of the cistern in one hour.

Multiplicative inverse of a number is called the reciprocal of a number.

NCERT Solutions for CBSE Class 8 Mathematics Chapter 14 Factorisation

Study Maths at your convenience with TopperLearning’s NCERT Solutions for CBSE Class 8 Maths Chapter 14 Factorisation. Revise the lessons on the division of algebraic expressions by going through our chapter solutions from CBSE Class 8 syllabus. Get over your fear of the concept of factorisation by practising numerous textbook solutions given by our subject experts.

- Factorisation of an expression means writing it as a product of its factors.
- An irreducible factor is a factor which cannot be expressed further as a product of factors.
- Factorisation using common factor method:

Step 1: Find the factors of the individual terms of the given expression.

Step 2: Find out all the common factors between the terms involved.

(same as finding HCF of terms)

Step 3: This common factor would be one factor of the given expression. Other factor would be the expression obtained on dividing the given expression by common factor. - Rearranging the given expression to a convenient form allows us to form groups leading to factorization. This is regrouping.
- Factorisation by regrouping terms

Step 1: Arrange the terms of the given expression in groups in such a way that all the groups have a common factor.

Step 2: Factorise each group.

Step 3: Take out the factor which is common to all such groups. - Factorisation using following identities:

i. a^{2}+ b^{2}+ 2ab = (a + b)^{2}

ii. a^{2}+ b^{2}- 2ab = (a - b)^{2}

iii. a^{2}- b^{2}= (a + b)(a - b)

iv. x^{2}+ (a + b)x + ab = (x + a)(x + b)

Method: Express the give expression as the LHS of the identities given above by choosing suitable values of a and b. Using identities, factorise the expression as RHS.

Practise with our solutions and understand the correct way to plot graphs based on the given data. Observe how data can be represented on the X-axis and the Y-axis of a graph.

- A bar graph is used to show comparison among categories.
- A pie graph is used to compare parts of a whole.
- A Histogram is a bar graph that shows data in intervals.
- A line graph displays data that changes continuously over periods of time.
- Two perpendicular number lines intersecting at point zero are called coordinate axes.
- The point of intersection of x-axis and y-axis is called origin and is denoted by ‘O’.
- The distance of a point from y-axis is called its x-coordinate and the distance of a point from x-axis is called its y-coordinate.
- The two coordinates x and y taken together for a point P constitutes an ordered pair P(x,y).
- The positions of the coordinates cannot be interchanged. Therefore P(x,y)≠Q(y,x), if x≠y.
- The x- coordinate of every point on y-axis is zero and the y-coordinate of every point on x-axis is zero.
- The x-coordinate of every point on the line parallel to y-axis is constant while y-coordinate of every point on the line parallel to x-axis is constant.
- A line graph which is a whole unbroken line is called a linear graph.
- Two quantities which vary directly can be plotted as a linear graph. Independent variable is generally taken on x axis the dependent variable is taken on y axis.
- Steps to draw a graph:

- Find out the relation between y and x.
- Calculate different values of y corresponding to the values of x.
- Tabulate the results.
- Plot the points.
- oin the points to obtain the graph.
