3 Example 1Use the Distributive Property Example 2Use Grouping Example 3Use the Additive Inverse Property Example 4Solve an Equation in Factored Form Example 5Solve an Equation by Factoring

4 Write each term as the product of the GCF and its remaining factors. Then use the Distributive Property to factor out the GCF. Use the Distributive Property to factor. First, find the CGF of 15x and. Factor each number. Circle the common prime factors. GFC: Rewrite each term using the GCF. Simplify remaining factors. Distributive Property

5 Answer: The completely factored form of is

6 Factor each number. Circle the common prime factors. Use the Distributive Property to factor. Rewrite each term using the GCF. Distributive Property Answer: The factored form of is GFC: or
