Solution for 15n^2+15n/15n^3 equation: 


n in (-oo:+oo)

((15*n)/15)*n^3+15*n^2 = 0

n^4+15*n^2 = 0

t_1 = n^2

1*t_1^2+15*t_1^1 = 0

t_1^2+15*t_1 = 0

DELTA = 15^2-(0*1*4)

DELTA = 225

DELTA > 0

t_1 = (225^(1/2)-15)/(1*2) or t_1 = (-225^(1/2)-15)/(1*2)

t_1 = 0 or t_1 = -15

t_1 = -15

n^2+15 = 0

1*n^2 = -15 // : 1

n^2 = -15

t_1 = 0

n^2+0 = 0

n^2 = 0

1*n^2 = 0 // : 1

n^2 = 0

n = 0

n = 0
