Whiteboard Practice One person from each row get the materials for the entire row!!
Practice x2 - 9 9x2 – 18x + 9
Still more Factoring!!!
Terms Zero property
Practice (x+12)(x+7) = 0 (z+2)(z+3) = 0
Practice x2 + 7x + 10 = 0 -x + x2 = 56
Practice x2 – 9x + 18 = 2x 2x2 – 9x – 35 = 0
Practice 3x2 + 34x + 11 = 0 y2 – 7y + 6 = -6
Whiteboard Practice One person from each row get the materials for the entire row!!
10.8 Factoring Using the Distributive Property Objective use the distributive property to factor polynomials Standards: A1.1.3, A1.6.6, A1.6.7, A1.8.2, A1.8.7
