  • 1. March 11, 2013
  • 2. Warm Up1. 2.
  • 3. Warm Up3. Find the length & width: A = 70 x+1 (x + 4)(x + 1) = 70 x+4 x2 + 5x + 4 = 70
  • 4. Warm Up4. 2x(x - 3) + 9(3 - x) 5. (x3 - 64x) 6. (x4 - 81) = (x2 - 9) (x2 + 9) = (x + 3)(x + 3)(x2 + 9)
  • 5. Khan: Poly 2 1. 3x3 + 6x2 –189x 2. -4x3 + 32x2 – 60x 3. 4x2 - 20x –56 4. -3x3 - 3x2 + 216x ***5. x2 - 6xy - 16y2 Everyone who completes 8 consecutive or 25total correct questions by Tuesday, 7:00 pm, will receive 100%
  • 6. Review: Perfect Square Trinomials : x2 + 10x + 25A. What is a perfect square trinomial? 1. The first term is a perfect square 2. The third term is a perfect square 3. Multiply the square root of the 1st termcoefficient by the square root of the 3rd termcoefficient. The 2nd term should be twice this amount.
  • 7. Review: Difference of Two SquaresAnother shortcut for factoring a trinomial is whenwe want to factor the difference of two squares. a2 – b2 = (a + b)(a – b) A binomial is the difference of two squares if: 1.Both terms are squares and 2.The signs of the terms are different. 9x2 – 25y2 – c4 + d4
  • 8. Review:Square of Sums: All +, + perfect square trinomials1. (x + 1) 2 factor into square of sum binomials.2. (3x + 1)2 The product of a Square of a Sum binomial (a + b)2 is: a2 + 2ab + b2
  • 9. Review:Square of a Difference: 2 All -, + perfect square trinomials factor1. (x - 4) into square of difference binomials.2. (3x - 1)2 The product of a Square of a difference binomial (a - b)2 is: a2 - 2ab + b2
  • 10. Test Review:1. x3 – 3x2 –16x + 48 2. x2 – 7x + 10 3. 8x2 + 2x - 3 4. 3a3b2 + 21a3b + 36a3
  • 11. Class Work: Factoring Frenzy: 1-20; AllMust Show Work on Scratch Paper!!
