expand (e^s+e^{2s}+e^{3s}+1)/((s+1)^2)

expand

\frac{e ^{s} + e ^{2 s} + e ^{3 s} + 1}{( s + 1 ) ^{2}}

\frac{e ^{s} + e ^{2 s} + e ^{3 s} + 1}{s ^{2} + 2 s + 1}

Solution steps

\frac{e ^{s} + e ^{2 s} + e ^{3 s} + 1}{( s + 1 ) ^{2}}

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

= \frac{e ^{s} + e ^{2 s} + e ^{3 s} + 1}{s ^{2} + 2 s + 1}

(x - 2) (x + 4)

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

\frac{x + 1 ( 2 - x ) ^{5}}{( x + 3 ) ^{7}}
