Δ = b2-4ac
Δ = 572-4·(-11)·0
Δ = 3249
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$w_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$w_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{3249}=57$
$w_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(57)-57}{2*-11}=\frac{-114}{-22}
=5+2/11
$
$w_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(57)+57}{2*-11}=\frac{0}{-22}
=0
