**Problem statement:**

x > y

xy 0

A: x^2/(y+1/y)

B: y^2(x+1/x)

**My question:**

The expression was simplified to

A: x^3 + x

B: y^3 + x

In the simplified expression, A is always greater. Tested with (x,y) values (1,-1) (2,1) and (-1,-2)

However, a direct substitution of values into the expression without simplification gives one case B > A and another of A > B. This is the 5lb response as well.
