**1. Homework Statement**

I'm not sure how to type "lim x-> 0 out using this forum's math symbols...

lim x→0 [[itex]\frac{1}{x\sqrt{1+x}}[/itex]-[itex]\frac{1}{x}[/itex]]

**2. Homework Equations**

**3. The Attempt at a Solution**

Honestly, I'm just not seeing how to manipulate the equation to get it to a point where I can find the solution. This isn't graded and isn't even for any class I'm in...I'm just curious. It's been 10 years since I've done anything like this, so I'm trying to get up to speed before I take Calculus again in the fall.
