Math Help - Limit Question

1. Limit Question

Lim x approaches 0 [(√x+4)-2]/x

I believe you multiply by the conjugate of √ but i'm getting lost on the algebra. Thanks for your help!

2. Re: Limit Question

$\frac{\sqrt{x+4}-2}{x}=\frac{(\sqrt{x+4}-2)(\sqrt{x+4}+2)}{x(\sqrt{x+4}+2)}=\frac{x}{ x(\sqrt{x+4}+2) }=\ldots$
