n in (-oo:+oo)
n*((2*n^3+6*n^2+4*n)/2) = 0
(n*(2*n^3+6*n^2+4*n))/2 = 0
2*n^3+6*n^2+4*n = 0
2*n*(n^2+3*n+2) = 0
n^2+3*n+2 = 0
DELTA = 3^2-(1*2*4)
DELTA = 1
DELTA > 0
n = (1^(1/2)-3)/(1*2) or n = (-1^(1/2)-3)/(1*2)
n = -1 or n = -2
2*n*(n+2)*(n+1) = 0
(2*n*n*(n+2)*(n+1))/2 = 0
( 2*n )
2*n = 0 // : 2
n = 0
