Exercise 3 Page 110

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

12(3c+2d)

Practice makes perfect
To factor the expression, we have to find the greatest common factor (GCF) between the terms. Let's rewrite each term as a product of its prime factors. 36c&= 2 * 2 * 3* 3 * c 24d&= 2 * 2 * 2 * 3* d In this case, the GCF is 2 * 2 * 3=12. We are going to rewrite each term as 12 multiplied by some factor. Then we will use the Distributive Property to factor the expression. Let's go!
