12x/32x^2+(-8x)/32x^2-6=0

We multiply all the terms by the denominator


12x+(-8x)-6*32x^2=0

Wy multiply elements

-192x^2+12x+(-8x)=0

We get rid of parentheses

-192x^2+12x-8x=0

We add all the numbers together, and all the variables

-192x^2+4x=0

a = -192; b = 4; c = 0;
Δ = b2-4ac
Δ = 42-4·(-192)·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*-192}=\frac{-8}{-384}
=1/48
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(4)+4}{2*-192}=\frac{0}{-384}
=0
