Δ = b2-4ac
Δ = 02-4·361·(-100)
Δ = 144400
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{144400}=380$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-380}{2*361}=\frac{-380}{722}
=-10/19
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+380}{2*361}=\frac{380}{722}
=10/19
