3. The Distributive Property

Continue to next subchapter

Exercise 1 Page 104

Be careful with negatives when distributing.

- x-9

Practice makes perfect

We want to simplify the given expression. To do it, we will use the Distributive Property. We will distribute -1 to the terms inside the parentheses.

- 1(x+9)

Distribute - 1

-1x+(- 1)9

(- a)b = - ab

- 1x-9

1* a=a

- x-9

The expression cannot be simplified further because - x and 9 are not like terms.
