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

The end solution:
$\sqrt{\Delta}=\sqrt{359924}=\sqrt{4*89981}=\sqrt{4}*\sqrt{89981}=2\sqrt{89981}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-600)-2\sqrt{89981}}{2*1}=\frac{600-2\sqrt{89981}}{2} $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-600)+2\sqrt{89981}}{2*1}=\frac{600+2\sqrt{89981}}{2} $
