expand (s+2)/((s+1)^2s)

expand

\frac{s + 2}{( s + 1 ) ^{2} s}

\frac{s + 2}{s ^{3} + 2 s ^{2} + s}

Solution steps

\frac{s + 2}{( s + 1 ) ^{2} s}

(s + 1)^{2} = s^{2} + 2 s + 1

= \frac{s + 2}{s ( s ^{2} + 2 s + 1 )}

Expand

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

= \frac{s + 2}{s ^{3} + 2 s ^{2} + s}

\frac{1}{( 1 + e ^{x} ) ^{2}}

\frac{( e ^{2 π} - 1 ) ( - 1 ) ^{n}}{π e ^{π} ( n ^{2} + 1 )}

- \frac{1}{12 ( 4 x + 3 ) ^{3}}

e^{x} (x^{2} + 5)

(t + x - 1)^{5}
