In mathematics, a polynomial's a finite length expression constructed from variables (also known as indeterminates) and constants, using the operations of addition, subtraction, multiplication, and constant non-negative whole number exponents. For example, 's a polynomial, but isn't, because its second term involves division by the variable x and also because its third term contains an exponent that isn't a whole number. Polynomials are one of the most important concepts in algebra and throughou… (More on Polynomials)
