1. WARM-UP Factor: 1. 2. I am picking the warm-up up today.

2. Factoring Trinomials when a=1 Unit 3-2

3. Remember FOILing? F – First O – Outer I – Inner L – Last

4. Factoring Factoring is the opposite of FOILing. Instead of putting two factors together by multiplying, we’re taking them apart.

5. Steps for Factoring 1. Determine the target product. This is found by multiplying the coefficients a and c together. 2. Determine the target sum. This is the coefficient b. 3. Determine which factors of the target product will add to get the target sum.

6. Example 1 Factor ( ) 1. Find the target product. a = 1 c = 7 2. Find the target sum. b = 8 3. Determine which factors of the product add to equal the sum. Place x at the front of both factors because x∙x=x 2
