Δ = 26848
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:
$\sqrt{\Delta}=\sqrt{26848}=\sqrt{16*1678}=\sqrt{16}*\sqrt{1678}=4\sqrt{1678}$
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-164)-4\sqrt{1678}}{2*4}=\frac{164-4\sqrt{1678}}{8} $
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-164)+4\sqrt{1678}}{2*4}=\frac{164+4\sqrt{1678}}{8} $
