We calculate fractions


(-4x)/54x^2+(-81x)/54x^2+46x/54x^2-4=0

We multiply all the terms by the denominator


(-4x)+(-81x)+46x-4*54x^2=0

We add all the numbers together, and all the variables

46x+(-4x)+(-81x)-4*54x^2=0

Wy multiply elements

-216x^2+46x+(-4x)+(-81x)=0

We get rid of parentheses

-216x^2+46x-4x-81x=0

We add all the numbers together, and all the variables

-216x^2-39x=0

a = -216; b = -39; c = 0;
Δ = b2-4ac
Δ = -392-4·(-216)·0
Δ = 1521
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1521}=39$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-39)-39}{2*-216}=\frac{0}{-432}
=0
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-39)+39}{2*-216}=\frac{78}{-432}
=-13/72
