# How do you factor 8ab^2 -12ab?

Mar 7, 2018

#### Answer:

You factor both terms, and take common factors "out of the brackets". You leave the rest inside.

#### Explanation:

$= \left(2 \cdot 2 \cdot 2 \cdot a \cdot b \cdot b\right) - \left(2 \cdot 2 \cdot 3 \cdot a \cdot b\right)$

Common is $= 2 \cdot 2 \cdot a \cdot b = 4 a b$

$= 4 a b \left(2 b - 3\right)$
