### Simplify so h = 0

Posted: August 31st, 2011, 8:11 pm
I'm a little bit confused on how to solve this

$\frac{\sqrt{x+h+1}-\sqrt{x+1}}{h}$

I multiplied numerator and denominator by the conjugate $\sqrt{x+h+1}+\sqrt{x+1}$

the numerator I got $x+h+2-x+1$ which simplifies to h + 1.

and the denominator:
$h(\sqrt(x+h+1)+\sqrt{x+1})$

that's all I got. I'm stuck now. don't know what to do next. I don't know if I made any errors
