(200x^2)-50=0

Solution for (200x^2)-50=0 equation:

(200x^2)-50=0

a = 200; b = 0; c = -50;
Δ = b2-4ac
Δ = 02-4·200·(-50)
Δ = 40000
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{40000}=200$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-200}{2*200}=\frac{-200}{400}
=-1/2
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+200}{2*200}=\frac{200}{400}
=1/2
