Δ = 8464
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{8464}=92$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-12)-92}{2*-2}=\frac{-80}{-4} =+20 $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-12)+92}{2*-2}=\frac{104}{-4} =-26 $
