Select the factors of x2 - 4x + 2y - 8 a. (x-2)(y+4) b. (x+2)(y-4) c. (x-4)(y+2) d. (x+4)(y-2)

None of the factors shown will give you the above number. In order to get the numbers that are on top, you would need two x's being multiplied by each other to get the x^2 value. Since none of the options have that, it is impossible to achieve that.
