(-128m^2)-7680m^2+448m+(-96m)=0

We get rid of parentheses

-128m^2-7680m^2+448m-96m=0

We add all the numbers together, and all the variables

-7808m^2+352m=0

a = -7808; b = 352; c = 0;
Δ = b2-4ac
Δ = 3522-4·(-7808)·0
Δ = 123904
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{123904}=352$
$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(352)-352}{2*-7808}=\frac{-704}{-15616}
=11/244
$
$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(352)+352}{2*-7808}=\frac{0}{-15616}
=0
