Question

simplifica la siguiente expresión [n!+(n-1)!/(n+1)!]-1

Answer 1

$[\frac{n! + (n-1)!}{(n+1)!} ] - 1\\\\.[\frac{n! + (n-1)n!}{(n+1)n!} - 1\\\\.[\frac{n![1 + (n-1) ]} {n!(n+1)} ] - 1\\\\.[\frac{[1 + (n-1)} {(n+1)} ] - 1\\\\.[\frac{1 + n-1 } {n+1} ] - 1\\\\\frac{1 + n-1 }{n+1} - 1\\\\\frac{n}{n+1} - 1\\\\\frac{n -(n+1)}{n+1}\\\\\frac{n -n - 1}{n+1}\\\\\frac{-1}{n+1}$
