a = 1; b = -1; c = -819823;
Δ = b2-4ac
Δ = -12-4·1·(-819823)
Δ = 3279293
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-1)-\sqrt{3279293}}{2*1}=\frac{1-\sqrt{3279293}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-1)+\sqrt{3279293}}{2*1}=\frac{1+\sqrt{3279293}}{2}
