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

$\sqrt{\Delta}=\sqrt{24336}=156$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-156}{2*676}=\frac{-156}{1352}
=-3/26
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+156}{2*676}=\frac{156}{1352}
=3/26
