A  = n3 + 3n2 + 2n

A = n(n2 + 3n + 2)

A = n[(n2 + n) + (2n + 2)]

A = n[n(n + 1) + 2(n + 1)]

A = n(n + 1)(n + 2)

+ Nếu n ⋮ 3 

⇒ A ⋮ 3; n và n + 1 là hai số tự nhiên liên tiếp nên sẽ có một số là số lẻ, một số là số chẵn nên n(n + 1) ⋮ 2 ⇒ A ⋮ 2

⇒ A \(\in\) B(2  ; 3); 2= 2; 3 = 3 ⇒ BCNN(2; 3) = 6 ⇒ A \(\in\) B(6) ⇒ A ⋮ 6

+ Nếu n không chia hết cho 3 thì n = 3k + 1 hoặc n = 3k + 2 ta có:

+ n = 3k + 1 thì n + 2 = 3k + 1 + 2 = 3k + ( 1 + 2) =  3k  +  3 ⋮ 3

+Nếu n = 3k  +  2 thì n + 1 = 3k + 2  + 1 = 3k + ( 2 + 1) = 3k +  3 ⋮ 3

Chứng minh tương tự với trường hợp A ⋮ 3 ở trên ta có A  là bội của 6 hay A ⋮ 6

Vậy A ⋮ 6 ∀ n \(\in\) Z+
