i didnt get this how u consider X and Y values when it is given in the question

If (x-5)(y+2) this means that X = 5

and Y = -2

thus XY = -10 and X > Y..

(x-5)(y+2) = 0 means that EITHER x=5 OR y=-2. For example, if x=5, then y can be any number. The same way, if y=-2, then x can be any number.

Bunuel, although your solution is perfect, I would just point out a

rewording suggestion on your last comment. (x-5)(y+2) =0 means that x = 5 OR y =-2 (without the EITHER). Obviously both equalities COULD happen simultaneously, but they don't HAVE TO happen simultaneously in order for the equation in stem to be valid
