We add all the numbers together, and all the variables

800x^2-9.4176=0

a = 800; b = 0; c = -9.4176;
Δ = b2-4ac
Δ = 02-4·800·(-9.4176)
Δ = 30136.32
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{-(0)-\sqrt{30136.32}}{2*800}=\frac{0-\sqrt{30136.32}}{1600}
=-\frac{\sqrt{}}{1600}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{30136.32}}{2*800}=\frac{0+\sqrt{30136.32}}{1600}
=\frac{\sqrt{}}{1600}
