3x/12x^2+(-8x)/12x^2-4-6=0

We add all the numbers together, and all the variables

3x/12x^2+(-8x)/12x^2-10=0

We multiply all the terms by the denominator


3x+(-8x)-10*12x^2=0

Wy multiply elements

-120x^2+3x+(-8x)=0

We get rid of parentheses

-120x^2+3x-8x=0

We add all the numbers together, and all the variables

-120x^2-5x=0

a = -120; b = -5; c = 0;
Δ = b2-4ac
Δ = -52-4·(-120)·0
Δ = 25
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{25}=5$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-5)-5}{2*-120}=\frac{0}{-240}
=0
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-5)+5}{2*-120}=\frac{10}{-240}
=-1/24
