Exercise 4 Page 419

Find the product of the common prime factors.

3(x+2)

Practice makes perfect

To use the Distributive Property in reverse, we have to find the greatest common factor (GCF) between the terms. 3x&= 3 * x 6&= 2 * 3 In this case, the GCF is the only common prime factor, 3. Let's factor out the GCF for our expression.

3x+6

Rewrite

Rewrite 3x as 3 * x

3 * x+6

Rewrite

Rewrite 6 as 2 * 3

3 * x+2 * 3

FactorOut

Factor out 3

3(x+2)
