Quadratic equations are polynomials, meaning strings of math terms. An expression like “x + 4” is a polynomial. They can have one or many variables in any combination, and the magnitude of them is ...

Solve quadratic equations by factorising, using formulae and completing the square. Each method also provides information about the corresponding quadratic graph.

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

In a boon to algebra students everywhere, a professor at Carnegie Mellon University has devised a simpler and more efficient way to solve problems involving the quadratic equation.

But he systematically set out word-­form linear and quadratic equations, with algorithmic methods for solving them — that is, for finding the "unknown numbers," our modern x 's and y 's.

Using the Graphing Calculator app, you can save equations and graph them. After you open the Graphing Calculator app, click the equations button and type in your equation using the custom keyboard.

Babylonians, in particular, would solve simultaneous equations to find the roots of a quadratic. Egyptians, Grecians, Indians, and Chinese peoples used graphical methods to solve the equations.

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