  1. Multiplying Polynomials Mrs. Reynolds 2/17/13

  2. 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

  3. Multiply the Points

  4. Monomial by a Polynomial • To multiply a polynomial by a monomial, distribute the monomial to each term in the polynomial. • Example:

  6. Multiply the Points

  7. Multiplying Polynomials by Polynomials • Use the distributive property to multiply polynomials.

  8. 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.
