a = -11; b = 101; c = 0;
Δ = b2-4ac
Δ = 1012-4·(-11)·0
Δ = 10201
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$w_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$w_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{10201}=101$
$w_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(101)-101}{2*-11}=\frac{-202}{-22}
=9+2/11
$
$w_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(101)+101}{2*-11}=\frac{0}{-22}
=0
