- 1. How to Factor ax 2 + bx + c Pick an example problem to use, and delete the others: 15x 2 + 26x + 8 2x 2 + 15x + 18 12x 2 + 23x + 5 6x 2 + 19x + 10 12x 2 + 8x + 1
- 2. Step 1:15x 2 +26+8 AC=15+8=120 B=26
- 3. Step 2:15x 2 +26+8 AC=15x 2 +8=120 Multiplied to 120 1,120 8,15 2,60 6,20 10,12
- 4. Step 3:15x 2 +26+8 AC=15x 2 +8=120 B= 6,20 < Match Multiplied to 120 1,120 8,15 2,60 6,20 < Match 10,12
- 5. Step 4: 15x 2 +26+8 15x 2 +26+8 15x 2 +6x+20x+8
- 6. Step 5:15x 2 +26+8 2x(2x+1)+8(2x+1) (2x+1) (2x+8)
