a = 6; b = -360; c = +3;
Δ = b2-4ac
Δ = -3602-4·6·3
Δ = 129528
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:

$\sqrt{\Delta}=\sqrt{129528}=\sqrt{36*3598}=\sqrt{36}*\sqrt{3598}=6\sqrt{3598}$
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-360)-6\sqrt{3598}}{2*6}=\frac{360-6\sqrt{3598}}{12}
$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-360)+6\sqrt{3598}}{2*6}=\frac{360+6\sqrt{3598}}{12}
