Any way to solve parametric inequations?

[jte]

I’m guessing this question might have been mooted because it pertains to a more complex / general use of the solve function — i.e., that the particular inequality given is not of direct interest (that the solve function is playing a part in a larger mathematical inquiry — a use of it is embedded in a larger CAS program, for example — or, perhaps, there is an interest in better understanding the CAS).

But, if not — if xy/(x+y)^2≤0, for integer x and y, is the object of direct interest — a related plot can be brought up in the Advanced Graphing app.
