Mathematician Finds Easier Way to Solve Quadratic Equations

[peacecalc]

Hello all,

it works on equations with complex roots, too.
The new way can be reduced to two steps:

\[ 1.\quad u^2 = \frac{b^2}{4} - c \qquad\qquad 2.\quad x_{1,2} = - \frac{b}{2} \pm \sqrt{u^2} \]

The traditional way:

\[ 1.\quad D = b^2 - 4c \qquad\qquad 2.\quad x_{1,2} = \frac{- b \pm \sqrt{D}}{2} \]

For me it seems to be a question of taste which way someone prefers. The only difference is:

\[ D = 4u^2 \]
