a = -1; b = 0; c = +553253.3161;
Δ = b2-4ac
Δ = 02-4·(-1)·553253.3161
Δ = 2213013.2644
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$c_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$c_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$c_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-\sqrt{2213013.2644}}{2*-1}=\frac{0-\sqrt{2213013.2644}}{-2}
=-\frac{\sqrt{}}{-2}
$
$c_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{2213013.2644}}{2*-1}=\frac{0+\sqrt{2213013.2644}}{-2}
=\frac{\sqrt{}}{-2}
