800-(200)/x^2=0

Solution for 800-(200)/x^2=0 equation:

800-(200)/x^2=0


Domain of the equation: x^2!=0

x^2!=0/

x^2!=√0

x!=0

x∈R


We multiply all the terms by the denominator


800*x^2-200=0

We add all the numbers together, and all the variables

800x^2-200=0

a = 800; b = 0; c = -200;
Δ = b2-4ac
Δ = 02-4·800·(-200)
Δ = 640000
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{640000}=800$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-800}{2*800}=\frac{-800}{1600}
=-1/2
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+800}{2*800}=\frac{800}{1600}
=1/2
