Ron Koren's Question:

Given the equation in vertex form, y=(x-1)^2 - 4, find the x-intercepts of the parabola. (Recall vertex form is y=a(x-h)^2 + k)

x=-1,3

Convert this vertex form equation to standard form. Use the discriminant to determine the x-intercepts. (Recall the discriminant is b^2 - 4ac)

y=x²-2x-3
