2-(180000/x^2)=0

Solution for 2-(180000/x^2)=0 equation:

2-(180000/x^2)=0


Domain of the equation: x^2)!=0

x!=0/1

x!=0

x∈R


We get rid of parentheses

-180000/x^2+2=0

We multiply all the terms by the denominator


2*x^2-180000=0

We add all the numbers together, and all the variables

2x^2-180000=0

a = 2; b = 0; c = -180000;
Δ = b2-4ac
Δ = 02-4·2·(-180000)
Δ = 1440000
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1440000}=1200$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-1200}{2*2}=\frac{-1200}{4}
=-300
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+1200}{2*2}=\frac{1200}{4}
=300
