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{-(1.8312)-\sqrt{3094.41889344}}{2*0.9156}=\frac{-1.8312-\sqrt{3094.41889344}}{1.8312}
$


$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1.8312)+\sqrt{3094.41889344}}{2*0.9156}=\frac{-1.8312+\sqrt{3094.41889344}}{1.8312}
