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

expand

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

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

Solution steps

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

e^{3 (s - 1)} = e^{3 s - 3}

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

Expand

(s + 1) e^{3 s - 3} : e^{3 s - 3} s + e^{3 s - 3}

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

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

5 (3 + 2)

\frac{( x ( x - 4 ) ( x - 9 ) )}{24}

(x - 2) (\frac{15}{8} x + \frac{24}{8})

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