Section Day 2 Obj: to find the binomial factors of quadratic expressions when a >1.
2
*Review. Multiply the binomials.
Ex. 1 (2π₯+6) 2 Ex. 2 (x β 4)(x + 5) Ex. 3 (3x + 1)(2x β 2) Ex. 4 (4x β 2)(2x β 3)
3
Factor. Ex. 1 π₯ 2 + 2x -15 Ex. 2 π₯ 2 - 7x β 8 Ex. 3 π₯ 2 + 3x -18
When a = 1: π₯ 2 + bx β c or π₯ 2 - bx - c then: (x + _____)(x - _____)
4
Factor when a > 1 (but prime).
Ex π₯ x β 3 Ex. 2 5 π₯ x - 12 Ex. 3 3 π₯ x - 6 Ex. 4 3 π₯ x + 21
5
Assign: Factoring WS #1 # 5,7,10,13,25, 39-47
