Wy multiply elements

(-128x^2)-2560x^2+448x+(-96x)=0

We get rid of parentheses

-128x^2-2560x^2+448x-96x=0

We add all the numbers together, and all the variables

-2688x^2+352x=0

a = -2688; b = 352; c = 0;
Δ = b2-4ac
Δ = 3522-4·(-2688)·0
Δ = 123904
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{123904}=352$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(352)-352}{2*-2688}=\frac{-704}{-5376}
=11/84
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(352)+352}{2*-2688}=\frac{0}{-5376}
=0
