We multiply parentheses

1/3x-8x-(2/3x-6)+12=0

We get rid of parentheses

1/3x-8x-2/3x+6+12=0

We multiply all the terms by the denominator


-8x*3x+6*3x+12*3x+1-2=0

We add all the numbers together, and all the variables

-8x*3x+6*3x+12*3x-1=0

Wy multiply elements

-24x^2+18x+36x-1=0

We add all the numbers together, and all the variables

-24x^2+54x-1=0

a = -24; b = 54; c = -1;
Δ = b2-4ac
Δ = 542-4·(-24)·(-1)
Δ = 2820
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{2820}=\sqrt{4*705}=\sqrt{4}*\sqrt{705}=2\sqrt{705}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(54)-2\sqrt{705}}{2*-24}=\frac{-54-2\sqrt{705}}{-48}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(54)+2\sqrt{705}}{2*-24}=\frac{-54+2\sqrt{705}}{-48}
