Δ = b2-4ac
Δ = 02-4·2·(-153.45)
Δ = 1227.6
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{1227.6}}{2*2}=\frac{0-\sqrt{1227.6}}{4}
=-\frac{\sqrt{}}{4}
$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{1227.6}}{2*2}=\frac{0+\sqrt{1227.6}}{4}
=\frac{\sqrt{}}{4}
