We calculate fractions


6x/12x^2+(-4x)/12x^2-5=0

We multiply all the terms by the denominator


6x+(-4x)-5*12x^2=0

Wy multiply elements

-60x^2+6x+(-4x)=0

We get rid of parentheses

-60x^2+6x-4x=0

We add all the numbers together, and all the variables

-60x^2+2x=0

a = -60; b = 2; c = 0;
Δ = b2-4ac
Δ = 22-4·(-60)·0
Δ = 4
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{4}=2$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(2)-2}{2*-60}=\frac{-4}{-120}
=1/30
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(2)+2}{2*-60}=\frac{0}{-120}
=0
