6xx-7x+2
Asked by dharmpalsingh533 | 21 Apr, 2019, 04:53: PM
6x^2 -7x + 2

Also assuming that you are required to factor the algebraic expression.

HINT and CONCEPT
Just try splitting middle terms.

-7x can be formed out by multiplying 6x^2 and 2 i.e. 12x^2. Such that you get two factors from this and sum up to get -7x.

NOTE- We also consider the coefficients of the variables, most of the times for middle term but you can also consider the variables while finding those.

Any guesses?

Check for -4x and -3x.
Multiply them, we get 12x^2.

So, the expression becomes,
6x^2 - 3x - 4x +2
Take common factors from first two and later two terms, we get

3x(2x - 1) -2(2x - 1)

This becomes

(3x - 2)(2x - 1)

These are the factors.
