a = -1; b = 11; c = +330;
Δ = b2-4ac
Δ = 112-4·(-1)·330
Δ = 1441
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{-(11)-\sqrt{1441}}{2*-1}=\frac{-11-\sqrt{1441}}{-2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(11)+\sqrt{1441}}{2*-1}=\frac{-11+\sqrt{1441}}{-2}
