Question 125726: Subtract. Simplify by removing a factor of 1 when possible.
5fc/f^2-c^2 - f-c/f+c

Answer by stanbon(75887)   (Show Source): You can put this solution on YOUR website!
(5fc)/(f^2-c^2) - (f-c)/(f+c)
---------
The lcm is f^2-c^2
----------
(5fc)/lcm - (f-c)^2/lcm
= [5fc-(f^2-2fc+c^2)]/lcm
= (c^2+7fc-f^2)/(f^2-c^2)
