x^2+1685x+709806=0

Solution for x^2+1685x+709806=0 equation:

x^2+1685x+709806=0

a = 1; b = 1685; c = +709806;
Δ = b2-4ac
Δ = 16852-4·1·709806
Δ = 1
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1}=1$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(1685)-1}{2*1}=\frac{-1686}{2}
=-843
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1685)+1}{2*1}=\frac{-1684}{2}
=-842
