# Polynomials

Polynomials are mathematical expressions that contain a sum of powers of indeterminate variables multiplied by coefficients. A core concept in algebra, polynomials are used in calculus and throughout all areas of mathematics. Wolfram|Alpha can compute several interesting properties of polynomials including extrema, roots, alternate forms, symmetry and parity. Additionally, polynomials can be factored, expanded or divided.
