Find out how to solve simultaneous equations using a graph in this Bitesize KS3 maths video.

Quadratic equations are polynomials, meaning strings of math terms. An expression like “x + 4” is a polynomial. They can have ...

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.

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