a = 12; b = -180; c = +3;
Δ = b2-4ac
Δ = -1802-4·12·3
Δ = 32256
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:

$\sqrt{\Delta}=\sqrt{32256}=\sqrt{2304*14}=\sqrt{2304}*\sqrt{14}=48\sqrt{14}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-180)-48\sqrt{14}}{2*12}=\frac{180-48\sqrt{14}}{24}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-180)+48\sqrt{14}}{2*12}=\frac{180+48\sqrt{14}}{24}
