2. STANDARD FORMFACTORED FORM Looks like… Examples Tells us about… MFM 2P

3. In y = (x – 4)(x + 5), Why are 4 and -5 the zeros? MFM 2P Lesson 3: Factored and Standard Form Equations

4. What are the zeros for y = (x + 5)(x – 1)? MFM 2P Lesson 3: Factored and Standard Form Equations

5. What are the zeros for y = (3x - 8)(x + 2)? MFM 2P Lesson 3: Factored and Standard Form Equations

6. Standard Form vs. Factored Form In the next unit, we’ll learn how to change from one form into the other. Factored Form like y = 3(x + 2)(x + 4) Factored Form like y = 3(x + 2)(x + 4) Standard Form like y = 3x 2 + 18x + 24 Standard Form like y = 3x 2 + 18x + 24 EXPAND FACTOR × ÷ MFM 2P

7. Sketch the parabola that has the following factored form and standard form equations: y = x 2 + 6x + 8 y = (x + 2)(x + 4)
