#x^2+8#

Explanation:

Here, we want to add our like terms. We essentially have the following:

#x^2+x-x-9+17#

I just rearranged the order, but I didn't change the value of this expression.

We see the #x# terms cancel out, and we're left with

#x^2-9+17#, which simplifies to

#x^2+8#

Hope this helps!
