Polynomial definition: A polynomial is a monomial or the sum or difference of monomials. Each monomial is called a term of the poynomial. Important!:Terms are seperated by addition signs and subtraction signs, but never by multiplication signs. A polynomial with one term is called a monomial.
In mathematics,  a coefficient is a multiplicative factor in some term of a polynomial, a series or any expression; it is usually a number, but may be any expression. In the latter case, the variables appearing in the coefficients are often called parameters, and must be clearly distinguished from the other variables.
