How am I supposed to do that? Getting back at school in 10 days.

Check out khan academy

Will do, thanks

Looks like you're being given an equation for a in terms of x, and you're being asked to solve for x in terms of a.

As your first two steps try subtracting the square root of x from both sides, then squaring both sides.

You first, need to learn to read french nigga, then you need to learn complex equations, then the last step!!! solve the problem.

Nah just messin' pal, I'm not good at math but that Khan academy sounds like a good idea, good luck.

>>177621
square both sides
leave radical on one side
square again
solve

Did that, and ended up with a gigantic mess.
Thanks, but I dont think this works, or at least not the way I do it.

>>177662
I kek'd thanks.

>>177766
lol of course it works. Do you imagine the answer is going to look particularly "neat"?

I suggest you do as well as you can and post what you did here so that if you're not doing it right, someone can help you or correct where you went wrong.

OP here, I solved it by squaring both times, and by not being completly retarded, just like you say I should have done. Thank you very much, it was pretty easy actually.

(> Implying I have the good answer)

Anyway, if anyone is curious,here is my result.
Thanks again

That's wrong because apparently you don't know how to square (a^2 - 1)

If you had checked to see if your answer was correct, you would have caught this. The easy check is to pick x = 0 from the first equation (from which it is obvious to see a=1) and then try a=1 for the equation solved for x.

On your solution, for a = 1, you get x = (1-1+1)/4 = -1/4

Oh shit, bumping the time I solve that

My bad, here is the correct answer.
For my defense, I fucked up by squaring three terms, not just 2.
