11x^2+67x+6=0
a = 11; b = 67; c = +6;
Δ = b2-4ac
Δ = 672-4·11·6
Δ = 4225
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{4225}=65$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(67)-65}{2*11}=\frac{-132}{22} =-6 $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(67)+65}{2*11}=\frac{-2}{22} =-1/11 $
