Concept in Definition ABC

At the request of the math is designated by the polynomial term to the sum of several monomials (algebraic expressions), because a polynomial is a expression algebraic, consisting of one or more variables, using only the arithmetic operations of addition, subtraction, multiplication and positive numerical exponents. The polynomial that has a single term is called a monomial, the one with two, binomials and the one with three, trinomials..

Although since ancient times, both the resolution of algebraic equations as well as the determination of the estate polynomials were the main concerns to be solved by mathematics, practice notation of the same and that is used at the moment, would only appear to be established until our days during the XV century.

Polynomial functions are called those that will arise from evaluate the polynomials on the variables from which they were defined and thus we find the following polynomial functions: polynomial function of grade 0, polynomial function of degree 1, polynomial function of degree 2, polynomial function of degree 3, and polynomial function of degree 4.

In practice, polynomials can be added and subtracted by grouping the terms together and simplifying the monomials that show similarities. Meanwhile, to multiply the polynomials, the methodology it will be to multiply each monomial term by the other monomial and again similar monomials will be simplified, in a later step.
