  4. Warm-Up • Find the GCF • 9, 12 • 51x, 85x2 • 30x3, 45x2, 105x • Use the distributive property to simplify • 3x(4x + 9) • (-3)(2x3 + 5)

  5. Section 10.8 Factoring Using a GCF SWBAT to factor a polynomials using a GCF

  6. What does it mean to factor? • Factoring a polynomial means to rewrite the polynomial as a product • Ex: The factored form of 6 is 2∙3

  7. Factoring Using a GCF • One way (and yes, you will learn the other ways) to factor a polynomial is by using the GCF

  8. Factoring Using a GCF • Step 1: Identify the GCF of the terms • Step 2: Divide the GCF from the rest of the terms • Step 3: Rewrite as a product (Use parenthesis)

  9. Example • Factor the polynomial below

  10. Example • Factor the polynomial below

  11. Example • Factor the polynomial below
