In other terms:
[(a/b)+(a+b)/(a/b)]/[(a/b)-(a-b)/(a+b)]
I tried to multiply both denominator and numerator by [b(a+b)(a-b)}\] but that didnt seem to work for me. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! [(a/b)+(a+b)/(a-b)]/[(a/b)-(a-b)/(a+b)]
= {[a(a-b)+b(a+b)]/[b(a-b)]} / {[a(a+b)-b(a-b)]/[b(a+b)]
= {[a^2+b^2]/b(a-b)]} / {[a^2-b^2]/[b(a+b)]}
Invert the denominator and multiply after cancelling where you can:
= (a^2+b^2)
