(x-1)(x-4)
(x + 2)(x - 9)
x2 + x - 12 = (x + 4) (x - 3)
(x+3)(x-3)
x2 - 9x + 20 = (x - 4)( x - 5)
(x + 2)(x - 4)
x(x + 3)(x - 4)
4(x - 1)(x + 1)
(x-1)(x-4)
It is the difference of squares. (x-4) and (x+4) <--- answer
It is x^2 -x -12 is (x+3)(x-4) when factored
x^2 - y^2 - 4 is in its simplest form.
x3 + 4x2 - 16x - 64 = (x + 4)(x + 4)(x - 4).
x2-5x-36 = (x-9)(x+4) when factored
(x - 4)(x - 3)
x(x-1)
(x + 2)(x - 9)
