## anonymous 4 years ago (1/2x) + (4x/x^2-1) - (2/x+1)

• This Question is Closed
1. anonymous

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

I might be waaay off because I'm tired but I got ... well that is definitely NOT what I got :P

3. anonymous

Is that the final answer?

4. anonymous

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

5. anonymous

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?

I just need to check my answer, sorry I don't mean to be rude. I just understand this already but I've not done it all in a while I know you are just trying to help me solve it myself but I need the correct answer please.

hmph..if you just want the answer then: http://www.wolframalpha.com/input/?i=%281%2F2x%29+%2B+%284x%2F%28x^2-1%29%29+-+%282%2F%28x%2B1%29%29

Ummm sorry but which is the answer :P

11. Directrix

[(5x - 1)] / [2x(x - 1)]

12. Mimi_x3

woops typo: $\large \frac{1-5x}{2x-2x^{2}}$

13. anonymous

I am going to fail my final :( I got 2(x)/ (x-1)(x+1) WHERE DID I GO WRONG!!! lol :(

14. Mimi_x3

hmm..wanna show me what you did:? :/

15. anonymous

I just erased it all but I guess I can draw it here... might take a while

16. Directrix

Show your work, and we'll look for possible error.

17. anonymous

I'm sorry I just can't do it I'm tired and sleepy and mad now this thing... idk

18. anonymous

No mouse and typing it gets me confused... sorry

19. anonymous

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
