We calculate fractions


108a^2/324a^2+54a/324a^2+(-108a)/324a^2=0

We multiply all the terms by the denominator


108a^2+54a+(-108a)=0

We get rid of parentheses

108a^2+54a-108a=0

We add all the numbers together, and all the variables

108a^2-54a=0

a = 108; b = -54; c = 0;
Δ = b2-4ac
Δ = -542-4·108·0
Δ = 2916
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$a_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$a_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{2916}=54$
$a_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-54)-54}{2*108}=\frac{0}{216}
=0
$
$a_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-54)+54}{2*108}=\frac{108}{216}
=1/2
