Who Remembers the Quadratic Equation?

 

Given a polynomial in which ax^2 + bx + c = 0, the quadratic equation, or “negative b plus or minus the square root of b squared minus 4 times a times c all divided by 2 times a” can solve for x. This formula has been seared in my brain since the 1980s. The quadratic equation (pictured above) is one of the main concepts in early algebra, and one that can be consistently confusing to new studentsBut now, apparently, there is a new way to solve for x that appeared in the most recent issue of Popular Mechanics.
