You can put this solution on YOUR website!
Let me know if I misunderstand your problem, sometimes with fractions, it's hard to know when denominators begin and end without parentheses.
2ab%5E1%2B4a%5E2y%5E%28-1%29%2Fa-7x%5E%28-1%29y%2Fy%5E%28-2%29
2ab%2B4a%5E%282-1%29%2Fy%5E1-7y%5E%281%2B2%29%2Fx%5E1
2ab%2B4a%2Fy-7y%5E3%2Fx
There are no like terms if I am reading this correctly.
The best we can do is give it a common denominator if you need it combined:
2abxy%2Fxy%2B4ax%2Fxy-7y%5E4%2Fxy
%282abxy%2B4ax-7y%5E4%29%2Fxy
Happy Calculating!!!
