-4n(6n-1)=0

Solution for -4n(6n-1)=0 equation:

-4n(6n-1)=0

We multiply parentheses

-24n^2+4n=0

a = -24; b = 4; c = 0;
Δ = b2-4ac
Δ = 42-4·(-24)·0
Δ = 16
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{16}=4$
$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(4)-4}{2*-24}=\frac{-8}{-48}
=1/6
$
$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(4)+4}{2*-24}=\frac{0}{-48}
=0
