You can put this solution on YOUR website!

A). 5x%2Fx%5E3+
B). %28x%5E2%2B3x%29%2Fx%5E3
C). %284x%2B12%29%2F%286x%2B18%29
D). %282x%2B7%29%2F%28x%2B3%29

For
A). I got 5%2Fx%5E2->correct

For B). I got %28x%5E4%2B3%29%2Fx%5E2 ->incorrect
%28x%5E2%2B3x%29%2Fx%5E3=>%28cross%28x%29%28x%2B3%29%29%2Fx%5Ecross%283%29%5E2=>%28x%2B3%29%2Fx%5E2
For C). I got 6x%2B18->incorrect
%284x%2B12%29%2F%286x%2B18%29=>cross%284%292cross%28%28x%2B3%29%29%2Fcross%286%293cross%28%28x%2B3%29%29=>2%2F3
and
for D). I got %282x%5E2%2B3x%2B7%29%2Fx.->incorrect
%282x%2B7%29%2F%28x%2B3%29 is already in simplest form
