Exercise 12 Page 113

Rewrite each term as a product of its prime factors to find the greatest common factor (GCF) between the terms.

3(3b+7)

Practice makes perfect
To factor the expression, we have to find the greatest common factor (GCF) between the terms. Let's then rewrite each term as a product of its prime factors. 9b&= 3* 3 * b 21&= 3* 7 In this case, the GCF is 3. We are going to rewrite each term as 3 multiplied by some factor. Then we will use the Distributive Property to factor the expression. Let's go!
9b+21
3 * 3b+ 3 * 7
3(3b+7)
