Asymptotic expansions of the distributions of the linear and the quadratic discriminant functions are derived. The expected misclassification probabilities of these two functions are compared when the ...

Learn and revise how to solve quadratic equations by factorising, completing the square and using the quadratic formula with GCSE Bitesize AQA Maths.

Unlike a linear, graph, a quadratic graph has an equation which includes an x squared term.

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.

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

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.
