Question

Simplify the following expression.
2x − 8y + 3x2 + 7y − 12x

Answer 1

The first thing I need to know is this. When you wrote 3x2, did you mean to write \(\large 3x^2\)?
It's important because they don't mean the same thing.

Answer 2

yes

Answer 3

Okay cool. So the thing to do here is group like terms. Do you know how to recognize when two terms are "like terms?"
