We get rid of parentheses

-256x^2-256x^2+96x-16x=0

We add all the numbers together, and all the variables

-512x^2+80x=0

a = -512; b = 80; c = 0;
Δ = b2-4ac
Δ = 802-4·(-512)·0
Δ = 6400
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{6400}=80$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(80)-80}{2*-512}=\frac{-160}{-1024}
=5/32
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(80)+80}{2*-512}=\frac{0}{-1024}
=0
