expand-(3s^3+2s^2-s-1)/((s+1)s^3)

expand

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

- \frac{3 s ^{3} + 2 s ^{2} - s - 1}{s ^{4} + s ^{3}}

Solution steps

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

Expand

(s + 1) s^{3} : s^{4} + s^{3}

= - \frac{3 s ^{3} + 2 s ^{2} - s - 1}{s ^{4} + s ^{3}}

\frac{( x + 1 )}{2 ( x - 1 ) ( 4 x + 1 )}

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

\frac{6 x ^{2} + 2}{( x ^{2} - 1 ) ^{3}}

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

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