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.

The quadratic equation has frustrated math students for millenniums. But a math professor at Carnegie Mellon University in Pittsburgh may have come up with a better way of solving it.

For example, consider this equation: 3x 2 -18x+9=0 It will have the same roots as the first one because if you divide both sides by 3, you get the first equation.
