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{-(0.01584)-\sqrt{0.0070937856}}{2*1}=\frac{-0.01584-\sqrt{0.0070937856}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0.01584)+\sqrt{0.0070937856}}{2*1}=\frac{-0.01584+\sqrt{0.0070937856}}{2}
