$\frac{6}{2\sqrt{|x|}-1}$

Consider both cases, the positive and negative.

Use the quotient rule.

$\frac{6}{2\sqrt{x}-1}$

$\frac{6}{2\sqrt{-x}-1}$

It helps to use parentheses. Do you mean this:

$ \frac 6 {\sqrt{|x|}} -1 $

or this:

$ \frac 6 {\sqrt{|x|-1}} $

or this:
$ \frac 6 {\sqrt{|x|}-1} $

In any event, do as Galactus suggested - you'll have one answer for the domain x>=0, and another for x <0.
