Trying to simplify an equation, but it's apparently wrong. So I'm solving a limit problem, where I try to see what happens as a function approaches x = 1. I just need to simplify an equation to solve that, which is what I'm stuck on right now.

The expression is

I first multiply the numerator and denominator by the denominator to get that ugly square root out of there. That gets me to

The denominator can be simplified to -x - 1.

I then plug 1 into the equation to find the limit I'm looking for.

Doing basic math on both the numerator and denominator, I simplify this down to 0 / -2, which is just 0. However, this apparently is the wrong answer. Can anyone see if they can find if I made an error anywhere? Thanks!
