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

The end solution:
$\sqrt{\Delta}=\sqrt{63360}=\sqrt{576*110}=\sqrt{576}*\sqrt{110}=24\sqrt{110}$
$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(240)-24\sqrt{110}}{2*120}=\frac{-240-24\sqrt{110}}{240} $
$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(240)+24\sqrt{110}}{2*120}=\frac{-240+24\sqrt{110}}{240} $
