you want to start out b rearrange the equation by putting like terms together.
Do you know how to factor?
I know how to factor, but why is it 2x^2-x? I am not catching on to something here.

I'm both at the movies with you and helping this person @thisSucks
In your equation, you have x^(2)-2x+x^(2)+x
There are 2x^2
and then you also have -2x +x which equals -x
Therefore your equation is 2x^2-x
You can't add an x^2 to an x, you can only add or subtract x^2's with other x^2's. The same goes for adding or subtracting x and x.
(Don't worry, we're not actually at the movies)
Oh alright. Because I knew 2x^2, and I knew -x but I was forgetting that we just have the -2x+x grouped separately from the x^2+x^2. Thank you!
