3. Factoring

4. Factoring a polynomial means expressing it as a product of other polynomials.

5. Look for the GCF! What is the GCF? 2x 3 + 4x 2 – 6x Factor OUT the GCF!!! Step #1

6. Step #2 2x(x 2 + 2x – 3) ax 2 + bx + c Find the numbers that are factors of ‘a·c’ GCF, leave it alone on the outside!

7. Step #3 ax 2 + bx + c Which of those factors in step 2 add to give you ‘b’?

8. 1) x 2 + 9x + 20 Find the numbers that are factors of ‘a·c’ and add to give you ‘b’.

9. Find 2 numbers that are factors of ‘a·c’ and add to give you ‘b’. 2) x 2 - 2x - 24 3) x 2 + 11x + 18

10. #4 Factor x 2 -3x -10

11. #5 Factor x 2 – 5x + 6

12. #6 x 2 + 4x – 12

13. #7 You try! x 2 - 9x + 20

14. #8 You try! x 2 +4x -32

15. Reminder!! Don’t forget to check your answer by multiplying!
