(x^2-180,000)/x^2=0

Solution for (x^2-180,000)/x^2=0 equation:

(x^2-180.000)/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


(x^2-180.000)=0

We get rid of parentheses

x^2-180.000=0

We add all the numbers together, and all the variables

x^2-180=0

a = 1; b = 0; c = -180;
Δ = b2-4ac
Δ = 02-4·1·(-180)
Δ = 720
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{720}=\sqrt{144*5}=\sqrt{144}*\sqrt{5}=12\sqrt{5}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-12\sqrt{5}}{2*1}=\frac{0-12\sqrt{5}}{2}
=-\frac{12\sqrt{5}}{2}
=-6\sqrt{5}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+12\sqrt{5}}{2*1}=\frac{0+12\sqrt{5}}{2}
=\frac{12\sqrt{5}}{2}
=6\sqrt{5}
