    (1/2x) + (2/(x-1)) + 2/(x+1) ) - 2/(x+1) = 1/2x + 2/(x-1)

    is 4x/(x^2-1) or (4x/x^2) - 1

    4x over x squared minus 1 so (4x/x^2-1)

    \[\frac{1}{2x} +\frac{4x}{x^{2}-1} -\frac{2}{x+1} = \frac{1}{2x} +\frac{4x}{(x-1)(x+1)} -\frac{2*(x-1)}{x+1*(x-1)} \] \[= \frac{1}{2x} +\frac{4x-2(x-1)}{(x-1)(x+1)} =\] Can you do it now?

    Wow man, I was never this frustrated with math before... I love math maybe I'm just tired. But if I don't finish this practice test I'm getting a fail on my final... it doesn't help that parents don't understand the pressure we get from school and keep bothering us about other things... It's the first time I feel like trashing everything... I guess this is why people drop out of high school huh? Man I need to chill
