Is this your question?
As it stands, the problem statement is extremely unclear.
... or this?
its the second one. sorry bout the unclarity, i dont know how to write equations on the internet. lol how fatuous of me. anywayz skeeter guessed it right so anyone care to explain? thanks
Well, how far can you get on your own?
We don't know what you know or been taught.
Is this a problem from math class?
Since , is the least common denominator of all the fractions. Start by multiplying both numerator and denominator by .
May be easier (less confusing) to first let x = a^2 - b^2 and y = a - b.
Simplify as much as you can with those, then substitute back in;

what i did was i used this rule that a/b + c/d equals ad+cb/bd. I tried to simplify the two fractions seperately but results weren't guud. this is a question for gr.10 math at school.
as recommended by Halls of Ivy ...
