The
quadratic function given by |
Graphical Solution | Symbolic Solution
Special Note |
All types of solution methods, including graphical, symbolic and numeric, give approximately the same solution to an equation. All are equally "good" solutions when all that is needed is an approximate solution. Exact solutions are usually found by using symbolic methods, as we use in traditional algebra. |
