Sometimes there's no better way to factor a quadratic equation than by simple bruteforce trial and error. Watch this free video algebra lesson to see how it's done. From Ramanujan to calculus cocreator Gottfried Leibniz, many of the world's best and brightest mathematical minds have belonged to autodidacts. And, thanks to the Internet, it's easier than ever to follow in their footsteps (or just finish your homework or study for that next big test).
