We calculate fractions


12x/24x^2+(-2x)/24x^2-5=0

We multiply all the terms by the denominator


12x+(-2x)-5*24x^2=0

Wy multiply elements

-120x^2+12x+(-2x)=0

We get rid of parentheses

-120x^2+12x-2x=0

We add all the numbers together, and all the variables

-120x^2+10x=0

a = -120; b = 10; c = 0;
Δ = b2-4ac
Δ = 102-4·(-120)·0
Δ = 100
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{100}=10$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(10)-10}{2*-120}=\frac{-20}{-240}
=1/12
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(10)+10}{2*-120}=\frac{0}{-240}
=0
