                Write the expression without using the factorial symbol.
(n+1)!/(n-1)!
my work:
(n+1)!/((n+1)(n-1)!)
=1/(n-1)?
Thanks in advance.

(n+1)!/(n-1)!
= (n+1)(n)(n-1)!/((n+1)(n-1)!
= n
    
(n+1)!/(n-1)!
= (n+1)(n)(n-1)!/((n+1)(n-1)!
= n

    You know what?
I looked at "my work" and assumed that was the starting question.
so here it goes once more
(n+1)!/(n-1)!
= (n+1)(n)(n-1)!/n-1)!
= n(n+1)
sorry
I should be more careful when reading questions.
