We multiply all the terms by the denominator


24x+(-4x)+1*3x^2=0

Wy multiply elements

3x^2+24x+(-4x)=0

We get rid of parentheses

3x^2+24x-4x=0

We add all the numbers together, and all the variables

3x^2+20x=0

a = 3; b = 20; c = 0;
Δ = b2-4ac
Δ = 202-4·3·0
Δ = 400
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{400}=20$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(20)-20}{2*3}=\frac{-40}{6}
=-6+2/3
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(20)+20}{2*3}=\frac{0}{6}
=0
