Is it possible to solve this?

Oh, sweet.

I was thinking you'd get the same answer, but I wasn't sure why I wasn't.

EDIT : Yeah, I feel dumb for not noticing it. Well, I mean... I noticed your mistake, but by the time I posted someone else had also. I didn't notice the other mistake, in that I took the a, b, c, etc for the quadratic formula from the post above me without checking them, which is why I was using 9 instead of -9.

Thanks for the continued help everyone, heh.
