a = 3; b = -801; c = +2;
Δ = b2-4ac
Δ = -8012-4·3·2
Δ = 641577
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-801)-\sqrt{641577}}{2*3}=\frac{801-\sqrt{641577}}{6}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-801)+\sqrt{641577}}{2*3}=\frac{801+\sqrt{641577}}{6}
