regardless of whether p is positive , 0 or negative,
result of p^2 is greater than or equal to 0.
similarly for any p^n where n is even.
for the given equation, since both terms are even power, the only possible solution is ...
(2x-1) = 0 and (y+2) = 0
x=(1/2) and y = -2
x-y = 5/2

Then firth piers are positive
The only way the sum are zero are both are zero
Then you could get x and y easily
