I have a math question!

It's not homework (I'm not in school at the moment.)
My dad took some placement tests earlier today, and he called me afterwards to ask me if I knew how to figure some of the problems he didn't remember how to do.
The one problem he said he had to solve and I couldn't recall how to figure was this, and now it's bugging me:
Simplify ((x^2)+5x+6))/(x+1)
For the sake of peace of mind, can someone remind me how this is done? I know I knew how to do it at some point ... it looks familiar, and I feel like in the past, it would've been fairly easy, but now I can't recall at all (it's been two years since I've taken any sort of math class, since I graduated high school.)
As an aside, my dad's already taken the test and it's done, so it's not to help him with his homework, either.

By simplify, it simply means to break up the equation if possible, so it is more simple to find an answer.
Meaning, you want to break it up so that x^2 + Ax + B = (x + C)(x + D) where if you multiplied the right side of the equation, you would get the left.
The answer:
So the simplified answer would be = (x + 2)(x + 3)/(x + 1)
Thanks!

I was thinking the same thing. Dad probably didn't remember it exactly? Because the way delro suggest would simplify to like (x + 2) or such.
Factoring the top terms is not simplifying anything. o_O
Yeah, if the bottom was x+2 or x+3, then it could divide/cancel out. AFAIK, you can't do anything more with (x+2)(x+3)/(x+1), though. Or maybe you can, and it's not really any simpler.
Because that can be simplified into (x-6).
just looks neater since i can't write x2 with a little superscript 2 >>
