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{3492.96}}{2*6}=\frac{0-\sqrt{3492.96}}{12}
=-\frac{\sqrt{}}{12}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{3492.96}}{2*6}=\frac{0+\sqrt{3492.96}}{12}
=\frac{\sqrt{}}{12}
