a = 6; b = -344; c = +1;
Δ = b2-4ac
Δ = -3442-4·6·1
Δ = 118312
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:

$\sqrt{\Delta}=\sqrt{118312}=\sqrt{4*29578}=\sqrt{4}*\sqrt{29578}=2\sqrt{29578}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-344)-2\sqrt{29578}}{2*6}=\frac{344-2\sqrt{29578}}{12}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-344)+2\sqrt{29578}}{2*6}=\frac{344+2\sqrt{29578}}{12}
