    help with factorising

    Hello! I'm having a bit of trouble working out how the following expression is factorised.

    1/4n2 (n+1)2 1/2n(n+1)

    Here is the answer

    = 1/4n(n+1)(n2+n-2)


    If anybody could show a working of how that answer is acheived it would be much appreciated.

    Thanks!
