15n2-n=0

Solution for 15n2-n=0 equation:

15n^2-n=0

We add all the numbers together, and all the variables

15n^2-1n=0

a = 15; b = -1; c = 0;
Δ = b2-4ac
Δ = -12-4·15·0
Δ = 1
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1}=1$
$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-1)-1}{2*15}=\frac{0}{30}
=0
$
$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-1)+1}{2*15}=\frac{2}{30}
=1/15
