The quadratic formula for a quadratic equation in the form of \(ax^2 + bx + c = 0\) is: \(x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}\). The first solution is \(\frac{(-6 ...

Everyone learns (and some readers maybe still remember) the quadratic formula ... using this method. Normalizing A to 1 is also an old trick and is sometimes called a reduced quadratic equation.

A mathematician and a computer scientist have just solved an "impossible" equation that has been considered unsolvable for ...
