a = 3; b = 9; c = -11;
Δ = b2-4ac
Δ = 92-4·3·(-11)
Δ = 213
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(9)-\sqrt{213}}{2*3}=\frac{-9-\sqrt{213}}{6}
$


$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(9)+\sqrt{213}}{2*3}=\frac{-9+\sqrt{213}}{6}
$
