I have a problem on finding the second derivative for this function:(adsbygoogle = window.adsbygoogle || []).push({});

[tex] \frac {x}{x^2-4} [/tex]

For the first derivative, I got:

[tex] \frac {-x^2-4}{(x^2-4)^2} [/tex]

Now here is where I am stuck! So far for the second derivative, I got this (Please check!):

[tex] \frac {-2x(x^2-4)^2-4x(-x^2-4)(x^2-4)}{(x^2-4)^4} [/tex]

I need this simplified! I know, it's an easy question. I may have lost my mind! :rofl:

Also please show me the steps. Thanks!

BTW. I am new to this forum and just learned the latex system. It is very complicated. Took me a while just to write out the problems above. I guess I gotta get used to it.
