If x and y are non-zero integers, and 64x^4 – 4y^4 = 8x^2 + 2y^2, which of the following could be the value of x2 in terms of y?	Choices
A) 2y^2	B) 2y	C) 2y^2/8	D) 2y^2-1/8	E) 2y^2+1/8
64x^4 – 4y^4 = 8x^2 + 2y^2   (8x^2 + 2y^2) (8x^2 - 2y^2) = 8x^2 + 2y^2   8x^2 - 2y^2 = 1   8x^2 = 2y^2+1   x^2 = 2y^2+1/8   Answer : 2y^2+1/8
