1. Factoring – Day 4 Factoring Trinomials Objective: To factor trinomials whose quadratic coefficient is 1

2. Warm-Up

3. Quadratic Equations ax 2 + bx + c -When you FOIL, this is the type of equation that you get.

4. Factoring Trinomials: 1.) Check for a GCF 2.) Find the factors that multiply to get the product of a(c) and the sum of b 3.) Rewrite the equation with 4 terms 4.) Factor by grouping. x 2 + 7x +12

5. Ex 1: Factor a.) x 2 + 16x + 28b.) y 2 – 9y + 8

6. Ex 2: Factor a.) x 2 – x – 30b.) t 2 + 10t - 24

7. Factor y 2 + 5y – 6 a.) (y + 3)(y + 2) b.) (y – 3)(y – 2) c.) (y + 6)(y – 1)

8. Ex 3: Factor c 2 – 16cd + 48d 2

9. Ex 4: Factor m 2 – 3m + 5

10. Factor y 2 + 4y – 5 a.) (y + 5)(y – 1) b.) (y – 5)(y + 1) c.) (y – 5)(y – 1)
