a = -3; b = 348; c = +1;
Δ = b2-4ac
Δ = 3482-4·(-3)·1
Δ = 121116
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:

$\sqrt{\Delta}=\sqrt{121116}=\sqrt{4*30279}=\sqrt{4}*\sqrt{30279}=2\sqrt{30279}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(348)-2\sqrt{30279}}{2*-3}=\frac{-348-2\sqrt{30279}}{-6}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(348)+2\sqrt{30279}}{2*-3}=\frac{-348+2\sqrt{30279}}{-6}
