a = 6; b = -27; c = -5;
Δ = b2-4ac
Δ = -272-4·6·(-5)
Δ = 849
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-27)-\sqrt{849}}{2*6}=\frac{27-\sqrt{849}}{12}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-27)+\sqrt{849}}{2*6}=\frac{27+\sqrt{849}}{12}
