Exercise 3 Page 311

Use the Distributive Property.

5a-10

Practice makes perfect

We want to simplify the given expression. To do it, we will use the Distributive Property. We will distribute 5 to the terms inside the parentheses.

5(a-2)

Distribute 5

5a-5(2)

Multiply

5a-10

The expression cannot be simplified further because 5a and 10 are not like terms.
