If x and y are integers such that x^2+4x+2y+6=2x^2+5x+y-6, we can deduce that y is
Select the correct option.
A) not an even	B) an even	C) a perfect square	D) an odd	E) a prime
x^2 + 4x + 2y + 6 = 2x^2 + 5x + y - 6   y = x^2 + x - 12   y = (x+4)(x-3) (Note that one factor is even and one factor is odd.)   Then y must be even.   The answer is an even.
