-324n^2+27n=0

a = -324; b = 27; c = 0;
Δ = b2-4ac
Δ = 272-4·(-324)·0
Δ = 729
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{729}=27$
$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(27)-27}{2*-324}=\frac{-54}{-648}
=1/12
$
$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(27)+27}{2*-324}=\frac{0}{-648}
=0
