Factoring Polynomials 1.Factor out the GCF. 2.If the polynomial has two terms or three terms, look for a difference of two squares, a product of two squares, or a pair of binomial factors. 3.If there are four or more terms, group terms and factor to find common binomial factors. 4.As a final check, make sure there are no common factors other than 1.
