if x and y are different integers and x^2=xy, which of the following must be true?	Pick one
A) x=0  B) x=6  C) x=3  D) x=2  E) x=1
(1) when x is 0, above eqn is satisfied regardless of y - true   (2) when x is not zero, the eqn is not satified   eg whn x = 2, 2*2 is not equal to 2 * 0 - false   (3) when x = -y, clearly product xy is negative.   but x^2 is positive - doesnt satify eqn   x=0nswer x=0
