a = 36; b = -180; c = +6;
Δ = b2-4ac
Δ = -1802-4·36·6
Δ = 31536
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:
$\sqrt{\Delta}=\sqrt{31536}=\sqrt{144*219}=\sqrt{144}*\sqrt{219}=12\sqrt{219}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-180)-12\sqrt{219}}{2*36}=\frac{180-12\sqrt{219}}{72} $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-180)+12\sqrt{219}}{2*36}=\frac{180+12\sqrt{219}}{72} $
