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
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;
easier for me, anyway!
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.
