Wy multiply elements

-550x^2+165x=0

a = -550; b = 165; c = 0;
Δ = b2-4ac
Δ = 1652-4·(-550)·0
Δ = 27225
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{27225}=165$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(165)-165}{2*-550}=\frac{-330}{-1100}
=3/10
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(165)+165}{2*-550}=\frac{0}{-1100}
=0
