expand ((-1)^nx^{n+2})/(3^{n+1)(n+2)}

expand

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

\frac{( - 1 ) ^{n} x ^{n + 2}}{3 ^{n + 1} n + 2 \cdot 3 ^{n + 1}}

Solution steps

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

Expand

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

= \frac{( - 1 ) ^{n} x ^{n + 2}}{3 ^{n + 1} n + 2 \cdot 3 ^{n + 1}}

(x + 3) (x - \frac{5}{2})

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

\frac{( 8 s - 16 )}{s ( s + 1 ) ( s ^{2} + 1 )}

- 2 (6 x + 5 y = 145)

\frac{( ln ( 50 ) - 5 ) ^{2}}{8}
