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.

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

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

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