x^2-998001=0

Solution for x^2-998001=0 equation:

x^2-998001=0

a = 1; b = 0; c = -998001;
Δ = b2-4ac
Δ = 02-4·1·(-998001)
Δ = 3992004
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{3992004}=1998$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-1998}{2*1}=\frac{-1998}{2}
=-999
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+1998}{2*1}=\frac{1998}{2}
=999
