Question

If one x-intercept for the parabola y=4x^2-4x-8 is (2,0), what is the other..?

Answer 1

do you know how to solve the equation?

Answer 2

No.

Answer 3

ok
first simplify by dividing by 4
4(x^2 - x - 2) = 0
x^x - 2x + x - 2 = 0
x(x - 2) + 1(x-2) = 0
(x - 2)(x +1) = 0
x = 2 or -1
the other x-intercept is at x = -1

answer is (-1,0)

Answer 4

there u go
