1. Factoring Unit – Day 7 Solving Polynomial Equations Mrs. Parziale

2. Do Now Solve the following: xy = 0 29ab = 0 -3xyz = 0

3. For all real numbers a and b: if ab = 0, then either a = 0 or b = 0 or they both equal zero. Zero-Product Property

4. Steps to Solving Polynomial Equations Another 4-Step Method Step 1: Get everything on one side with zero on the other side. Step 2: Factor the polynomial Step 3: Set each factor equal to zero Step 4: Solve for the variable

5. You Try These Solve by factoring:

6. You Try These Solve by factoring:

7. Closure When solving a polynomial equation, what step is done first? What is true about a and/or b when ab = 0 Explain how you would solve the following: 6x 2 + 18x + 16 = 4
