How to Solve Quadratic Equations? Solving Quadratics

For solving the quadratics by graphing, we first have to graph the quadratic expression (when the equation is in the standard form) either manually or by using a graphing calculator. For any quadratic equation ax2 + bx + c = 0, the sum of the roots = -b/a the product of the roots = c/a.
