Question 150769: add algebraic fractions:
a-1/a+1 + a+1/a-1
I used the LCM of (a+1)(a-1)
(a-1)(a-1)/(a+1)(a-1) + (a+1)(a+1)/(a+1)(a-1)
a^2-2a+1+a^2+2a+1/(a+1)(a-1)
2a^2+2/(a+1)(a-1)
2(a^2+1)/(a+1)(a-1)
ok now I'm stuck, can I do anymore?
Is what I've done right so far?
Thank You for your time.

You can put this solution on YOUR website! (a-1)/(a+1) + (a+1)/(a-1)
I used the LCM of (a+1)(a-1)
(a-1)(a-1)/(a+1)(a-1) + (a+1)(a+1)/(a+1)(a-1)
[a^2-2a+1+a^2+2a+1]/(a+1)(a-1)
2a^2+2/[(a+1)(a-1)]
[2(a^2+1)]/[(a+1)(a-1)]
ok now I'm stuck, can I do anymore?
-----------
No, you cannot do any more.
Cheers,
