Multiplying Polynomials by Polynomials • Use the distributive property to multiply polynomials.
FOIL • We can multiply them in any order so long as each of the first two terms gets multiplied by each of the second two terms. • But there is a handy way to help us remember to multiply each term called "FOIL". • It stands for "Firsts, Outers, Inners, Lasts": • So you multiply the "Firsts" (the first terms of both polynomials), then the "Outers", etc.
