Simplify as much as possible ((n+2)!) / (n!)

[From: ] [author: ] [Date: 12-08-13] [Hit: ]

(n + 2)(n + 1)n!/(n!(n + 2)(n + 1) = n^2 + 3n + 2-(n+2)!/n! = (n + 2)(n + 1) = n^2 + 3n + 2-(n+2)(n+1)(n!) / n!......

((n + 2)!)/(n!) =
(n + 2)(n + 1)n!/(n!) =
(n + 2)(n + 1) = n^2 + 3n + 2

(n+2)!/n! = (n + 2)(n + 1) = n^2 + 3n + 2

(n+2)(n+1)(n!) / n!

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