Learn how to form, manipulate and solve quadratic equations. Revise expansion of expressions and factorising and forming quadratics.

Solving simultaneous equations with one linear and one quadratic Algebraic skills of substitution and factorising are required to solve these equations.

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

Many former algebra students have painful memories of struggling to memorize the quadratic formula. A new way to derive it, overlooked for 4,000 years, is so simple it eliminates the need.

The option to input an equation is at the top-right corner of the calculator window. As you can see from the picture above, you can compute both linear and quadratic equations in the calculator.
