27x/54x^2+(-2x)/54x^2+2x/54x^2-1=0

We multiply all the terms by the denominator


27x+(-2x)+2x-1*54x^2=0

We add all the numbers together, and all the variables

29x+(-2x)-1*54x^2=0

Wy multiply elements

-54x^2+29x+(-2x)=0

We get rid of parentheses

-54x^2+29x-2x=0

We add all the numbers together, and all the variables

-54x^2+27x=0

a = -54; b = 27; c = 0;
Δ = b2-4ac
Δ = 272-4·(-54)·0
Δ = 729
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{729}=27$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(27)-27}{2*-54}=\frac{-54}{-108}
=1/2
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(27)+27}{2*-54}=\frac{0}{-108}
=0
