We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:
$\sqrt{\Delta}=\sqrt{44352}=\sqrt{576*77}=\sqrt{576}*\sqrt{77}=24\sqrt{77}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-252)-24\sqrt{77}}{2*9}=\frac{252-24\sqrt{77}}{18} $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-252)+24\sqrt{77}}{2*9}=\frac{252+24\sqrt{77}}{18} $
