This document contains information about polynomials: - A polynomial is an expression with variables and constants using only addition, subtraction, multiplication, and non-negative integer exponents. Each term is a constant multiplied by one or more variables raised to a non-negative integer power. - The degree of a polynomial is equal to the highest exponent in any term. Terms are usually written in descending order of degree. - If two polynomials are equal for all values of the variable, then the coefficients of like powers must be equal, making the polynomials identical.
