polynomialpolynomial, mathematical expression which is a finite sum, each term being a constant times a product of one or more variables raised to powers. With only one variable the general form of a polynomial is a _{0} x ^{ n }+ a 1 x n  1+ a 2 x n  2+…+ a n  1 x + a_{ n } where n is a positive integer and a 0, a 1, a 2, … , a_{ n } are any numbers. An example of a polynomial in one variable is 11 x 4  3 x 3+7 x 2+ x  8. The degree of a polynomial in one variable is the highest power of the variable appearing with a nonzero coefficient; in the example given above, the degree is 4.
