Find the roots of the quadratic equation

WebWhen finding the roots (x intercepts), don't use the quadratic formula unless you can show tha factoring is not possible. -. For each of the following quadratics, calculate the x and y intercepts, vertex and the maximum or minimum output (y value). a. y = x² + 2x - 5. WebIn Sal's completing the square vid, he takes the exact same equation (ax^2+bx+c = 0) and he completes the square, to end up isolating x and forming the equation into the quadratic formula. In other words, the quadratic formula is simply just ax^2+bx+c = 0 in terms of x. So the roots of ax^2+bx+c = 0 would just be the quadratic equation, which is:
