  1. 5-13 Using Factoring to Solve Problems • Objective: to solve problems by writing and factoring quadratic equations.

  2. 5-13 Using Factoring to Solve Problems • Example 1: A decorator plans to place a rug in a 9 m by 12 m room so that uniform strip of flooring around the rug will remain uncovered. How wide will the strip be if the area of the rug is to be half of the room?

  3. 5-13 Using Factoring to Solve Problems 12 m • Example 1: • Step1: What is width of strip uncovered. • Step 2: Let x = the width of strip • Then 12 – 2x = length of the rug x 9m x
