LO (Learning Objective):
• To factor polynomials.
Ex. 1) Factor each polynomial completely.
a) 𝑥 ! + 10𝑥 " + 24𝑥
b) 5𝑦 # − 125𝑦 $
Ex. 2) Factor completely:
a) 𝑥 ! − 64
b) −16𝑥 % − 250𝑥 "
c) 6𝑧 " − 24𝑧 + 24
Ex. 3) Factor 𝑥 ! − 2𝑥 " − 9𝑥 + 18 completely.
Factoring Polynomials in Quadratic Form
Ex. 4) Factor completely:
a) 625𝑥 & − 256
You Try! Factor:
𝑥 # + 6𝑥 ! − 16
b) 2𝑥 '! + 10𝑥 ( + 8𝑥 %
