  1. Adv. Algebra factoring review • This review should prepare you for the factoring test in Advanced Algebra. Read each problem , work out the answer, then check your answer by clicking on the mouse.

  2. 1. Multiply (x +4)(x2 - 4) • X3+ 4x2 - 4x -16

  3. 2. What is the GCF of the following: 18xy, 27x2? • 9x

  4. 3. Multiply : 4x(3x-4)(2y+5) • 24x2y + 60x2 - 32xy - 80x

  5. 4. Factor: 6x2 + 12x • 6x(x+2)

  6. 5. Factor: 5x2 - 125 • 5(x+5)(x-5)

  7. 6. Factor: x2 + 8x + 15 • (x + 5)(x + 3)

  8. 7. Factor: 4x2 - 6x + 2 • 2(2x-1)(x-1)

  9. 8. Factor 8x3 -10x2-12x • 2x(4x+3)(x-2) , don’t forget to pull what’s in common out first

  10. 9. Factor: 2xy-10x+y-5 • (2x + 1)(y - 5)

  11. 10. Factor: 15x + 10 - 6x3 -4x2 • (5 - 2x2)(3x + 2)

  12. 11. Solve: (x+2)(x-3) = 0 • -2 and 3

  13. 12. Solve: x2 +4x - 5=0 • -5 and 1

  14. 13. Solve : x2 = 25 • 5 and -5

  15. 14. Solve: 2x2 + 5x = 3 • -3 and 1/2

  16. 15. What must you do to an equation first before you solve it? • Set it equal to zero (if it has a degree more than one)

  17. 16. What does factoring mean? • Break something up it into simpler parts • Write as multiplication of primes

  18. What must you do first in ANY factoring problem? • Factor out Greatest Common Factor

  19. THE END!!
