Presentation Transcript

  1. Factoring by GCF and Grouping Algebra II CP

  2. GCF • Greatest Common Factor a. x² - 6x b. 15x³ + 10x² - 5x

  3. Grouping • 6xy – 8x + 15y – 20 • 12x² - 15xy – 16x + 20 y

  4. Factoring to Solve • (2x + 1)(x – 5) = 0 • 12x² = 36x Must set everything equal to zero first. Factor, then solve.

  5. Ex last one: • Solve each equation. a. 4a² = 10a b. x² + 3x + 4x + 12 = 0
