b^2-f^2 = (b-f)(b+f)

So, is the answer (b-f)(b+f)? which I think goes at the bottom as a fraction, and if it does, what is the number that goes on top?
However, I could be wrong, can you please help me understand? Thank you.

=(10bf)/((b+f))(b-f)) - (b-f)/(b+f)
Now multiply second term top and bottom by (b-f) to get a common denominator
(10bf)/((b+f))(b-f)) - (b-f)(b-f)/((b+f)(b-f))
You can take it from here.
