WebFeb 11, 2016 · 2 Answers Sorted by: 2 As noted in the comments, here is a useful hint: If $r \geq 0$, then $$\frac { (n-2)!} { (n-2-r)!} = \frac { (n-2) (n-3) \dots (n-2-r + 1) (n-2-r)\dots (2) (1)} { (n-2-r)!}$$ If the $r$ in the expression makes it confusing, try letting $r$ equal a positive integer. Say, $r = 2$.
