1. Section Day 2
Obj: to find the binomial factors of quadratic expressions when a >1.

2. *Review. Multiply the binomials.
Ex. 1 (2𝑥+6) 2
Ex. 2 (x – 4)(x + 5)
Ex. 3 (3x + 1)(2x – 2)
Ex. 4 (4x – 2)(2x – 3)

3. Factor. Ex. 1 𝑥 2 + 2x -15 Ex. 2 𝑥 2 - 7x – 8 Ex. 3 𝑥 2 + 3x -18
When a = 1:
𝑥 2 + bx – c or 𝑥 2 - bx - c then:
(x + _____)(x - _____)

4. Factor when a > 1 (but prime).
Ex 𝑥 x – 3
Ex. 2 5 𝑥 x - 12
Ex. 3 3 𝑥 x - 6
Ex. 4 3 𝑥 x + 21
