We get rid of parentheses

-48x^2-96x^2+16x-12x=0

We add all the numbers together, and all the variables

-144x^2+4x=0

a = -144; b = 4; c = 0;
Δ = b2-4ac
Δ = 42-4·(-144)·0
Δ = 16
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{16}=4$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(4)-4}{2*-144}=\frac{-8}{-288}
=1/36
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(4)+4}{2*-144}=\frac{0}{-288}
=0
