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 ...

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.

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

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.

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

You don't have to know how to solve a quadratic formula to do this activity." The students will use this lesson again for their final project.

There’s seemingly no end to how many things you can describe with a quadratic equation. Babylonians, in particular, would solve simultaneous equations to find the roots of a quadratic.

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