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

Answer 1

Nathan Axel

#-27z#

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

#-27z#

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

To factor the expression 3z^2 - 3z^2 - 27z, first combine like terms to simplify the expression. Since the terms 3z^2 and -3z^2 cancel each other out, we are left with -27z. So, the factored expression is simply -27z.
