The Distributive Property

Algebra 1 Unit 2 Lesson 7

Think-pair-share:

Pre-requisites:

Multiplying integerspositive x positive =

positive x negative =

negative x negative =

Identifying like terms

SMOTD

Distributive Property Rule:

a (b + c) = ab + ac

3(40 + 2) -3(40 + 2) -3(-40 - 2)

Practice Problems:

6(6 + 3)

-2(8 + 7)

-5(-5 - 5)

Distributive Property Rule:

a (b + c) = ab + ac

3(x + 2) -3(x + 2) -3(-x - 2)

SMOTD

Practice Problems:

6(x + 9)

-2(x + 7)

-5(-x - 10)

You will get an A for math if you can answer this in 3 seconds:

what is 5 x 37?

Use the concept of D.P. to make multiplication easier:

6 x 52 =

2 x 87 =

3 x 38 =

4 x 106 =

Solve:

2 (3x + 4y)

Combining like terms

1 - 5+ 7 + 4- 3

2x + 5x - 5x+ 2 - 7

1 - 5 + 7 + 4 - 3

+ 2x 5x 2 - 5x2 - 7+ 5
