expand ((n+2)!)/((n+1)!)

expand

\frac{( n + 2 ) !}{( n + 1 ) !}

n + 2

Solution steps

\frac{( n + 2 ) !}{( n + 1 ) !}

Cancel the factorials:

\frac{n !}{( n - m ) !} = n \cdot (n - 1) \dots (n - m + 1), n > m

\frac{( n + 2 ) !}{( n + 1 ) !} = (n + 2)

= n + 2

(\frac{6 - y}{2})^{2}

\frac{( 4 y ^{2} - 7 y - 12 )}{y ( y + 2 ) ( y - 3 )}

\frac{p + 1 + r ( t + 1 )}{1 + r}

\frac{- ( W ) ( L + x ) ^{2}}{2} + (2 L W x)

\frac{16}{3} - \frac{8}{3}
