When a polynomial is a product of two or more polynomials, each of the later polynomials is called its factors.

The method of expressing a given polynomial as a product of two or more polynomials is called factorization.

If a given polynomial contains a common factor which may be either a constant or a variable, we divide each term separately by this factor.

If the polynomial has an even number of terms, then the terms are first arranged in groups such that each group has a common factor.
