expand (n^2+2n+1)(n-2)!

expand

(n^{2} + 2 n + 1) (n - 2)!

n^{2} (n - 2)! + 2 n (n - 2)! + (n - 2)!

Solution steps

(n^{2} + 2 n + 1) (n - 2)!

= (n - 2)! (n^{2} + 2 n + 1)

Distribute parentheses

= (n - 2)! n^{2} + (n - 2)! \cdot 2 n + (n - 2)! \cdot 1

= n^{2} (n - 2)! + 2 n (n - 2)! + 1 \cdot (n - 2)!

Multiply:

1 \cdot (n - 2)! = (n - 2)!

= n^{2} (n - 2)! + 2 n (n - 2)! + (n - 2)!
