We calculate fractions


(-240x^2)/1728x^2+3888x/1728x^2+(-1872x)/1728x^2=0

We multiply all the terms by the denominator


(-240x^2)+3888x+(-1872x)=0

We get rid of parentheses

-240x^2+3888x-1872x=0

We add all the numbers together, and all the variables

-240x^2+2016x=0

a = -240; b = 2016; c = 0;
Δ = b2-4ac
Δ = 20162-4·(-240)·0
Δ = 4064256
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{4064256}=2016$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(2016)-2016}{2*-240}=\frac{-4032}{-480}
=8+2/5
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(2016)+2016}{2*-240}=\frac{0}{-480}
=0
