a = -1; b = 0; c = +108.09;
Δ = b2-4ac
Δ = 02-4·(-1)·108.09
Δ = 432.36
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{432.36}}{2*-1}=\frac{0-\sqrt{432.36}}{-2}
=-\frac{\sqrt{}}{-2}
$
$c_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{432.36}}{2*-1}=\frac{0+\sqrt{432.36}}{-2}
=\frac{\sqrt{}}{-2}
