a = -0.785; b = 0; c = +63585.5;
Δ = b2-4ac
Δ = 02-4·(-0.785)·63585.5
Δ = 199658.47
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-\sqrt{199658.47}}{2*-0.785}=\frac{0-\sqrt{199658.47}}{-1.57}
=-\frac{\sqrt{}}{-1.57}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{199658.47}}{2*-0.785}=\frac{0+\sqrt{199658.47}}{-1.57}
=\frac{\sqrt{}}{-1.57}
