1. When factoring any polynomial the first step is to look for a ______________________________.

2. Factoring could be described as reversing _____________________________________________.

3. A polynomial that cannot be factored would be called ___________________________________.

4. A2 – B2 would be factored using the pattern called a _____________________________________.

5. Expressions with four or more terms can sometimes be factored ___________________________.

Factor the following completely.

6. 3x3 + 6x2 – 15x

7. 4x2 – 25                                                      11. 3xy – 6y + 5x – 10

8. x2 + 6x + 9                                                   12. 4x2 – 36

9. x2 – 9x + 20                                                  13. x3 – 27

10. 6x2 – x – 2                                                  14. x2 + 100
