(-108x^2)/288x^2+192x/288x^2+(-240x)/288x^2=0

We multiply all the terms by the denominator


(-108x^2)+192x+(-240x)=0

We get rid of parentheses

-108x^2+192x-240x=0

We add all the numbers together, and all the variables

-108x^2-48x=0

a = -108; b = -48; c = 0;
Δ = b2-4ac
Δ = -482-4·(-108)·0
Δ = 2304
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{2304}=48$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-48)-48}{2*-108}=\frac{0}{-216}
=0
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-48)+48}{2*-108}=\frac{96}{-216}
=-4/9
