Thanks for that.

For instance: Problems like x^{-3/2} - 2x^{-1/2} + x^{1/2} are extremely simple for me, whereas problems such as (x^2+1)^{1/2} - 10(x^2+1)^{-1/2} are hit or miss and always confuse me somewhere in the process. I know I'm missing something very simple somewhere in the process, but it eludes me.

Thanks for the suggestion; I didn't know about that site. Unfortunately, unless I'm missing something, I run into the same issue as with Khan Academy. These sample problems are extremely simple. I'm looking for something where you actually factor out whole binomials (as well as positive/negative...

Thank you for the swift reply. I definitely understand the mistake I was making. For some reason the subtraction in the middle threw me off. You put me in the right direction. I eventually came to the following: [(x^2-4)(x^2+3)^{1/2}]-[(x^2-4)^2(x^2+3)^{3/2}]...

Hello, First time poster here. After lurking about the forums for a couple days I feel as if this question may be overly rudimentary; regardless, I'm stuck. This is not a homework assignment but preparation for an upcoming precalculus class. (x^2-4)((x^2+3)^1/2) - ((x^2-4)^2)...
