So, if x*y > than zero, we know that neither x nor y can be zero, because anything multiplied by zero is equal to zero.  Now, we also know, that a negative times a negative is positive, and a positive times a positive times a positive is positive.

x and y can either both be negative, or both be positive.  

They cannot be zero, or one negative, one positive.
