This guy found an easier way to solve quadratic equations

SOLVING THOSE pesky quadratic equations from high school algebra just became a lot easier. Dr Po-Shen Loh, a mathematician at Carnegie Mellon University in Pittsburgh, has derived an easier way to solve the classic sequence of squares, roots, and variables.

Quadratic equations are often used in business to forecast profits, find minimum and maximum points, or determine the trajectory of a moving object. They include an x2, and teachers use the equations to show students how to find
