Use graphing to solve quadratic equations You know by now how to solve a quadratic equation using factoring. Another way of solving a quadratic equation is to solve it graphically. The roots of a quadratic equation are the x-intercepts of the graph. Example: Solve the equation. Graph the equation. This could either be done by making a table of values as we have done in previous sections or by computer or a graphing calculator. The parabola cross the x-axis at x = -2 and x = 5.

Quadratic equation Starting with a quadratic equation in standard form, ax2 + bx + c = 0. 1  Divide each side by a, the coefficient of the squared term. 2  Subtract the constant term c/a from both sides. 3  Add the square of one-half of b/a, the coefficient of x, to both sides. This completes the square, converting the left side into a perfect square.
