The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{19044}=138$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-138}{2*529}=\frac{-138}{1058}
=-3/23
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+138}{2*529}=\frac{138}{1058}
=3/23
