WebUse the standard form of a quadratic equation y = ax2 + bx + c as the starting point for finding the equation through the three points. y = ax2 + bx + c Create a system of equations by substituting the x and y values of each point into the standard formula of a quadratic equation to create the three equation system. WebSal rewrites the equation y=-5x^2-20x+15 in vertex form (by completing the square) in order to identify the vertex of the corresponding parabola.
