We calculate fractions


(-256x^2)/128x^2+96x/128x^2+(-80x)/128x^2=0

We multiply all the terms by the denominator


(-256x^2)+96x+(-80x)=0

We get rid of parentheses

-256x^2+96x-80x=0

We add all the numbers together, and all the variables

-256x^2+16x=0

a = -256; b = 16; c = 0;
Δ = b2-4ac
Δ = 162-4·(-256)·0
Δ = 256
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{256}=16$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(16)-16}{2*-256}=\frac{-32}{-512}
=1/16
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(16)+16}{2*-256}=\frac{0}{-512}
=0
