Δ = b2-4ac
Δ = 02-4·123·(-18.45)
Δ = 9077.4
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{9077.4}}{2*123}=\frac{0-\sqrt{9077.4}}{246}
=-\frac{\sqrt{}}{246}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{9077.4}}{2*123}=\frac{0+\sqrt{9077.4}}{246}
=\frac{\sqrt{}}{246}
