### Multiplying Monomials

• When multiplying monomials take the following steps:

• Multiply the constants.

• Multiply the variables with the same base.

Ex.

Constants Variables multiplied by the same base

### Monomial by a Polynomial

• To multiply a polynomial by a monomial, distribute the monomial to each term in the polynomial.

• Example:

### 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.
