Question 66818
(y^-5   -  3y^5x^-2   +   y^5)     x^-2
________________________________________
(x^2    -     p       +   x^-2)    y^5
---------------------------------

Put that x^-2 in the denominator and multiply thru by it to get:
(1/y^5   -  3y^5/x^2   +   y^5)
_________________________________
(x^4    - x^2p       +  1)y^5

There is not much more you can do with this except distribute in the denominator to get:
[(x^2   -  3y^10   +  x^2y^10)
________________________________
(x^4 -x^2p  + 1)x^2y^10

[(x^2   -  3y^10   +  x^2y^10)
_________________________________
[x^6y^10 - x^4py^10 +x^2y^10]


I'm sure you could stop at a different point
but this is as good as any.
It's a mess of a problem.
