We calculate fractions


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

We multiply all the terms by the denominator


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

Wy multiply elements

-72x^2+6x+(-2x)=0

We get rid of parentheses

-72x^2+6x-2x=0

We add all the numbers together, and all the variables

-72x^2+4x=0

a = -72; b = 4; c = 0;
Δ = b2-4ac
Δ = 42-4·(-72)·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*-72}=\frac{-8}{-144}
=1/18
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(4)+4}{2*-72}=\frac{0}{-144}
=0
