We calculate fractions


54x^2/72x^2+12x/72x^2+(-48x)/72x^2-4=0

We multiply all the terms by the denominator


54x^2+12x+(-48x)-4*72x^2=0

Wy multiply elements

54x^2-288x^2+12x+(-48x)=0

We get rid of parentheses

54x^2-288x^2+12x-48x=0

We add all the numbers together, and all the variables

-234x^2-36x=0

a = -234; b = -36; c = 0;
Δ = b2-4ac
Δ = -362-4·(-234)·0
Δ = 1296
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1296}=36$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-36)-36}{2*-234}=\frac{0}{-468}
=0
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-36)+36}{2*-234}=\frac{72}{-468}
=-2/13
