Δ = b2-4ac
Δ = 02-4·(-1)·38689
Δ = 154756
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$c_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$c_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{154756}=\sqrt{4*38689}=\sqrt{4}*\sqrt{38689}=2\sqrt{38689}$
$c_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-2\sqrt{38689}}{2*-1}=\frac{0-2\sqrt{38689}}{-2}
=-\frac{2\sqrt{38689}}{-2}
=-\frac{\sqrt{38689}}{-1}
$
$c_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+2\sqrt{38689}}{2*-1}=\frac{0+2\sqrt{38689}}{-2}
=\frac{2\sqrt{38689}}{-2}
=\frac{\sqrt{38689}}{-1}
