Quadratic equation

You are given a quadratic equation $ax^2 + bx + c = 0$ ($a \ne 0$). Its discriminant is positive, so the equation has two distinct real roots. Find both roots:

$D = b^2 - 4ac, \qquad x_{1,2} = \frac{-b \mp \sqrt{D}}{2a}$

A single line with three integers $a$, $b$, $c$ ($|a|, |b|, |c| \le 1000$, , ). It is guaranteed that .

A single line with two numbers — the roots in increasing order, each with exactly 2 digits after the decimal point.

When $a$ is negative, $\dfrac{-b - \sqrt{D}}{2a}$ turns out to be the larger root — compare the roots before printing and write the smaller one first.
