Exercise 10 Page 211

Recall the Distributive Property.

4+16x

Practice makes perfect

We want to simplify the given expression. To do it, we will use the Distributive Property. We will distribute 4 to the terms inside the parentheses.

4(3+4x-2)

Distribute 4

4(3)+4(4x)-4(2)

Multiply

12+16x-8

CommutativePropAdd

Commutative Property of Addition

12-8+16x

Subtract term

4+16x

Since 4 and 16x are not like terms, the expression cannot be simplified further.
