Answer by MathGuyJoe(20) About Me  (Show Source):
You can put this solution on YOUR website!
Assuming this is what your expression looks like:
+15x%28x-y%29%2F5x%5E3y%28x-y%29+


You can cancel out the (x-y) elements on top & bottom, leaving you with:
+15x+%2F+5x%5E3y+


From here you can reduce each element independently, leaving you with:
+3+%2F+x%5E2y+


Which is answer B. Hope that helps. Let me know if any step is unclear.
