Multiplying monomials
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
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
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.
