$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-\sqrt{17827177.76}}{2*28}=\frac{0-\sqrt{17827177.76}}{56}
=-\frac{\sqrt{}}{56}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{17827177.76}}{2*28}=\frac{0+\sqrt{17827177.76}}{56}
=\frac{\sqrt{}}{56}
