1. Review Question: System of Equations

2. HW

3. Quick Quiz Factor the monomial. 1. 18pq²
Find the GCF of each set of monomials.
2. 30, x, 10x³
Factor each polynomial.
4. 9x² - 3x x³ + 16x²

4. 1)Factor trinomials. 2) Solve equations by factoring.
Factoring Be able to:
1)Factor trinomials.
2) Solve equations by factoring.

5. F-O-I-L Foil these binomials:
(x + 5) (x + 3)
(x + 7) ( x + 2)
(x – 3) (x – 4)
Do you recognize any pattern developing with an answer to a problem?

6. F-O-I-L Backward
1. x² + 9x + 18
2. x² + 7x + 10
3. x² - 6x + 8
4. x² - 2x – 15
To “Foil” backward in this way is how you factor a trinomial.

7. Factor these: Remember your terms must be factors of the last term and add to the middle term.
5. m² + 3x + 2
6. x² + 10x + 21
7. x² + 3x – 18
8. r² - r - 12

8. Solving Equations 9. x² + 4x + 3 = 0 10. x² - 8x + 15 = 0
11. n² - 4n – 21 = 0
