Solution for (3n^2+10n+3)/(n+3) equation: 


D( n )

n+3 = 0

n+3 = 0

n+3 = 0

n+3 = 0 // - 3

n = -3

n in (-oo:-3) U (-3:+oo)

(3*n^2+10*n+3)/(n+3) = 0

3*n^2+10*n+3 = 0

3*n^2+10*n+3 = 0

DELTA = 10^2-(3*3*4)

DELTA = 64

DELTA > 0

n = (64^(1/2)-10)/(2*3) or n = (-64^(1/2)-10)/(2*3)

n = -1/3 or n = -3

(n+3)*(n+1/3) = 0

n+1/3 = 0

n+1/3 = 0 // - 1/3

n = -1/3

n = -1/3
