What is the difference between polynomials and algebric expression?
A polynomial is a mathematical expression consisting of a sum of terms, each term including a variable or variables raised to a power and multiplied by a coefficient. The simplest polynomials have one variable. A one-variable (univariate) polynomial of degree n has the following form:
anxn + an-1xn-1 + ... + a2x2 + a1x1 + a0x0
where the a's represent the coefficients and x represents the variable.
Note: Every polynomial is an algebri expression but every alg. expression is not a polynomial.
