Question

One x-intercept for a parabola is at the point (-4,0) use the factor method to find the other x-intercept for the parabola defined by this equation:

y=-x^2-2x+8

Answer 1

I used synthetic division to find the other x-intercept, which is another way of finding zeros of a quadratic. There's more than one way to get there so I found the other zero to exist at (2, 0)
