  1. Unit 8 Lesson 3

  2. Let’s Review • Mathematical Properties/classify numbers • Multi-Step Equations • Functions, Slope • Absolute Value • Proportions/Percent of increase/decrease • Inequalities : When to switch sign? • Graphing Standard/Slope-Intercept Form • Sequences, Arithmetic, Geometric • Growth and Decay • Pythagorean Theorem, Radicals • B.A.G.

  3. “I can…” • … I can identify the greatest common monomial factor of a polynomial and factor it out of a polynomial • M(F&A)-10-3 • M(F&A)-10-4

  4. What does “Factoring” mean? • Factor Trees

  5. 2 Volunteers • What similarities do they both have?

  6. “Greatest Common Factor”

  7. Now, Putting it together with the “Distributive Property”

  8. Recall multiplying two binomials using FOIL

  9. Today, we are going the opposite direction

  10. What factors of “c” add to “b” • Using a t - chart

  11. Example

  12. Example

  13. Example

  14. Why do this? • When you factor you can ‘find roots,’ ‘find zeros,’ ‘find x-intercepts,’ or ‘solve quadratic equations.’

  15. Factoring with ax^2

  16. Example

  17. Examples 1-3

  18. Examples 4-6

  19. Helipad-find area of blue regionsmore tomorrow…
