We use following formulas to calculate our solutions:
$p_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$p_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$p_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(7.26216861548)-\sqrt{52.7390929997}}{2*-8.015435}=\frac{-7.26216861548-\sqrt{52.7390929997}}{-16.03087}
$
$p_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(7.26216861548)+\sqrt{52.7390929997}}{2*-8.015435}=\frac{-7.26216861548+\sqrt{52.7390929997}}{-16.03087}
