x^2=160000

Solution for x^2=160000 equation:

x^2=160000

We move all terms to the left:

x^2-(160000)=0

a = 1; b = 0; c = -160000;
Δ = b2-4ac
Δ = 02-4·1·(-160000)
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*1}=\frac{-800}{2}
=-400
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+800}{2*1}=\frac{800}{2}
=400
