# How do you factor 3z^2-3z^2-27z?

Jun 19, 2018

$- 27 z$

#### Explanation:

I'm going to do this problem assuming you meant to have two second-degree terms:

The first two terms cancel, which leaves us with

$- 27 z$

This expression, since it is a monomial, cannot be factored.

Hope this helps!
