You can put this solution on YOUR website!
remember a negative power is the same as 1 divided by the positive power:
3x%5E%28-3%29%2A2y%5E%28-2%29%2A2x=%282x%29%2F%283x%5E3%2A2y%5E2%29'
Now note that x%2F%28x%5E3%29=1%2F%28x%5E2%29:
3x%5E%28-3%29%2A2y%5E%28-2%29%2A2x=%282%29%2F%283x%5E2%2A2y%5E2%29,
=%282%29%2F%286x%5E2%2Ay%5E2%29,
=1%2F%283x%5E2%2Ay%5E2%29.
This can also be written in polynomial form: %281%2F3%29x%5E%28-2%29%2Ay%5E%28-2%29
I hope this helps.
