Hey!
Recently I ran across a really confusing question in my calc lab. (n-3)! (n-1) / n!
So far I was able to simplify the question down to n!-4n+6 which looks a bit like something that I could factor but then I starting running across all of these sites that said you have to have this fancy eq for n!=(n (n-1)!). Would that be applicable here and if so how would I integrate it into my solution? If I'm not on the right track then any help would be appreciated to get me to the proper answer. Thanks!
