You can put this solution on YOUR website!
You can't solve it (no = sign), just simplify it.
:
4r%5E2-25s%5E2
------------------
2r%5E2%2B3rs-20s%5E2
:
Both the numerator & denominator can be factored:
%282r-5s%29%282r%2B5s%29
------------------
%282r-5s%29%28r%2B4s%29
:
Note that (2r-5s)'s will cancel, leaving you with:
%282r%2B5s%29
-----------
%28r%2B4s%29
:
Did this make sense to you?
