Wy multiply elements
2X^2-20000X+1=0
a = 2; b = -20000; c = +1;
Δ = b2-4ac
Δ = -200002-4·2·1
Δ = 399999992
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:
$\sqrt{\Delta}=\sqrt{399999992}=\sqrt{4*99999998}=\sqrt{4}*\sqrt{99999998}=2\sqrt{99999998}$
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-20000)-2\sqrt{99999998}}{2*2}=\frac{20000-2\sqrt{99999998}}{4} $
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-20000)+2\sqrt{99999998}}{2*2}=\frac{20000+2\sqrt{99999998}}{4} $
