MULTIPLYING AND FACTORING CHAPTER 8 SECTION 2 AND 3

OBJECTIVES I can multiply a monomial by a polynomial I can factor a monomial from a polynomial. I can multiply two binomials using foil method.

DISTRIBUTIVE PROPERTY Distributive property can be used to multiply a monomial and a polynomial. How might you simplify the following: 5n(3n3 + n2 +8)

FACTORING Factoring a polynomial is like doing the distributive property in reverse. The goal is to divide everything in the problem by a common term.

ON PAGE 493… Look at Problem 2 and 3.

ON PAGE 494… Try problems #1-8 on your own.

MULTIPLYING BINOMIALS There are several ways to multiply binomials 1.Distributive Property 2.Using a Table 3.Foil Method 4.We will concentrate on using FOIL method.

FOIL METHOD F = First Terms O = Outer Terms I = Inner Terms L = Last Terms

FOIL (A + B) (C + D) = AC + AD +BC + BD You end up multiplying everything in the second term by everything in the first term.

ON PAGE 300… Look at Problem 3 and 4…. Try the “Got It” examples for those problems.

ON PAGE 501… Try problems #1-7 on your own.
