Wy multiply elements

-264k^2+11k=0

a = -264; b = 11; c = 0;
Δ = b2-4ac
Δ = 112-4·(-264)·0
Δ = 121
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$k_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$k_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{121}=11$
$k_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(11)-11}{2*-264}=\frac{-22}{-528}
=1/24
$
$k_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(11)+11}{2*-264}=\frac{0}{-528}
=0
