Ax2 bx c 0 follow these steps. Solving Quadratic Equations by Completing the Square. In symbol rewrite the general form.
In this case we were asked for the x -intercepts of a quadratic function which meant that we set the function equal to zero.
To find the roots of a quadratic equation in the form. I If a does not equal 1 divide each side by a so that the coefficient of the x 2 is 1. Now lets start the completing-the-square process. X 2 3 x -28 0 x23x28 0.
