A quadratic equation is drawn as a curve on a set of axes. This type of curve is called a parabola and it is symmetrical. To draw the graph we need coordinates. We generate these coordinates by ...

Revise the methods of solving a quadratic equation including factorising and the quadratic formula. See a worked example of how to solve graphically.

A mathematician at Carnegie Mellon University has developed an easier way to solve quadratic equations. Here's the secret.

As you can see from the picture above, you can compute both linear and quadratic equations in the calculator. This calculator allows you to plot multiple equations on a single graph, which can ...
