expand 9(n(n+1)(2n+1))

Solution

expand

9 (n (n + 1) (2 n + 1))

Solution

18 n^{3} + 27 n^{2} + 9 n

Solution steps

9 (n (n + 1) (2 n + 1))

Remove parentheses:

(a) = a

= 9 n (n + 1) (2 n + 1)

Expand

(n + 1) (2 n + 1) : 2 n^{2} + 3 n + 1

= 9 n (2 n^{2} + 3 n + 1)

Expand

9 n (2 n^{2} + 3 n + 1) : 18 n^{3} + 27 n^{2} + 9 n

= 18 n^{3} + 27 n^{2} + 9 n
