  2. 3.) 5( x - 2y ) 2 3 3

  3. 3 2 4.) 2x + 1 4x + 6x + 3x Long Division

  4. 2 6.) (x - 8x + 6) / (x + 2)

  5. Factoring Goal – Students will be able to factor polynomials.

  6. Factoring the sum & difference of two cubes Sum of Two cubes a + b = (a + b) ( a - ab + b ) Difference of two cubes a - b = (a – b) (a + ab + b ) 3 2 2 3 2 2

  7. Example 3 • 125 + z

  8. Factoring by grouping 3 2 8y - 4y - 50y + 25

  9. Determine whether the given binomial is a factor of the polynomial P(x). (x – 8); p(x) = x - 8x + 8x - 64 4 5
