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

expand

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

\frac{1}{n ^{3} + 3 n ^{2} + 2 n}

Solution steps

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

Expand

n (n + 1) (n + 2) : n^{3} + 3 n^{2} + 2 n

= \frac{1}{n ^{3} + 3 n ^{2} + 2 n}

(sec (x) - 1)^{2}

(x + 2 i)^{2}

\frac{1}{x ^{3}} (\frac{1}{3 x ^{2}} - \frac{x}{2})^{9}

cos (θ) (csc (θ) - sec (θ))

\frac{180 ( n - 2 )}{n}
