a = -1; b = 20020; c = 0;
Δ = b2-4ac
Δ = 200202-4·(-1)·0
Δ = 400800400
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{400800400}=20020$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(20020)-20020}{2*-1}=\frac{-40040}{-2}
=+20020
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(20020)+20020}{2*-1}=\frac{0}{-2}
=0
