what is polynomial

A polynomial is a mathematical expression consisting of variables, constants, and exponents that are combined using mathematical operations such as addition, subtraction, multiplication, and division (no division operation by a variable) . The word polynomial comes from the Greek words "poly" meaning "many" and "nominal" meaning "terms," so altogether it means "many terms". Polynomials can have one or more terms, but not an infinite number of terms. Based on the number of terms present in the expression, it is classified as monomial, binomial, and trinomial. The degree of a polynomial is the highest power of the variable in the polynomial. Polynomials are used in various fields of mathematics, including algebra and algebraic geometry.
