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

Solution

expand

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

Solution

4 n^{3} + 6 n^{2} + 2 n

Solution steps

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

Remove parentheses:

(a) = a

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

Expand

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

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

Expand

2 n (2 n^{2} + 3 n + 1) : 4 n^{3} + 6 n^{2} + 2 n

= 4 n^{3} + 6 n^{2} + 2 n
