Question

Simplify -3x^2 + 2y^2 + 5xy - 2y + 5x^2 - 3y^2

Answer 1

This is just combining like terms

Did you have any idea about how to go about this?

Answer 2

No, but I've been trying to figure this out for almost an hour already.

Answer 3

Ok so lets start with -3x²
The only thing similar to it is:
5x²
When you add these up you get
2x^4
