# Thread: Factor with two variable

1. ## Factor with two variable

I need to factor

$6x^2+xy-2y^2$

I don't know what to do with this

This looks difficult, but try to think of it as a normal quadratic, just ignore the $y$ for the moment, we then get $6x^2+x-2$.

I'm sure you can factorise this to get $(3x+2)(2x-1)$.

If we put the $y$ back in, we then get $(3x+2y)(2x-y)$.

Multiply that out, what do you get?

Hope this helps
