Exercise 25 Page 421

Find the product of the common prime factors.

6(3x+1)

Practice makes perfect

To use the Distributive Property in reverse, we have to find the greatest common factor (GCF) between the terms. 18x&= 2 * 3 * 3 * x 6&= 2 * 3In this case, the GCF is the product of the common prime factors. 2 * 3 = 6 Let's factor out the GCF for our expression.

18x + 6

Rewrite

Rewrite 18x as 6 * 3x

6 * 3x + 6

Rewrite

Rewrite 6 as 6 * 1

6 * 3x + 6 * 1

FactorOut

Factor out 6

6(3x+1)
