How do you write #y=x^2-2x+8# in vertex form and identify the vertex, y intercept and x intercept?
x of vertex:
y of vertex:
Find x-intercepts by solving quadratic equation:
Use the new AC Method to solve quadratic equation. Compose factor pairs of c = 8: (-2, 4). This sum is -2 + 4 = 2 = -b. Then the 2 real roots (x -intercepts) are: -2 and 4.
