Answer by Edwin McCravy(20060) (Show Source): You can put this solution on YOUR website!







The LCD of all 4 denominators, top and bottom is u²w².
Multiply every term top and bottom by u²w² (put it over 1 so
everything will be a fraction, and it'll be easier to see:




Then we cancel what will cancel:



And we have no fractions on the top or bottom:



We factor out uw on top, and factor the bottom as the difference
of squares:



Finally we cancel the (2w-u)'s



And the final answer is:
