Δ = 369616
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:
$\sqrt{\Delta}=\sqrt{369616}=\sqrt{16*23101}=\sqrt{16}*\sqrt{23101}=4\sqrt{23101}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-608)-4\sqrt{23101}}{2*4}=\frac{608-4\sqrt{23101}}{8} $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-608)+4\sqrt{23101}}{2*4}=\frac{608+4\sqrt{23101}}{8} $
