USING ALGEBRA TILES TO MODEL THE MULTIPLICATION OF TWO BINOMIALS On Core page 301 Model the multiplication of (2x +1)(x+3) using the algebra tiles on your desk. Discuss the Reflect Questions with your group

Using the Distributive Property to multiply Polynomials (3s2 – s – 1) (s + 2) S(3s2 – s – 1) + 2(3s2 – s – 1)

FOIL METHOD of MULTIPLYING BINOMIALS will only work when multiplying binomials First refers to the first terms of each binomial. Outer refers to the two terms on the outside of each binomial. Inner refers to the two terms on the inside of each binomial Last refers to the last terms of each binomial (7x -1)(3x-5)

Work Independently – Can you use the foil method on your own. Refer to your OnCore book page 303 Word on Reflect Questions with your group Now work on Example 3 (page 304) Work Independently – Can you use the foil method on your own.
