A quadratic equation has the general form of: y=ax² + bx + c It can be converted to the vertex form in order to determine the vertex of the parabola. It has the standard form of: y = a(x+h)² - k where h, k are the vertex points. y=-2x^2 + 2x+ 2 y=-2(x^2 - x) + 2 y + 1/4 = -2 (x^2 -x +1/4) + 2 y = -2 (x - 1/2)^2 + 7/4 Therefore, the vertex is (-1/2, -7/4) at x = 6, y = -58
