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

expand

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

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

Solution steps

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

Expand

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

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

\frac{( 2 x + 9 ) ^{2}}{4}

(cos (θ) - x)^{2}

e^{i (\frac{3 y \cdot a}{2} - \frac{2 π}{3})}

\frac{d}{d x} ((x + 1) ln (x)) - x + 1

\frac{4 e ^{x}}{( 4 + e ^{x} ) ^{2}}
