expand (4s)/((s-1)(s+1)^2)

expand

\frac{4 s}{( s - 1 ) ( s + 1 ) ^{2}}

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

Solution steps

\frac{4 s}{( s - 1 ) ( s + 1 ) ^{2}}

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

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

Expand

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

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

\frac{7 + 2 s + 6 e ^{- 4 s}}{( s + 2 ) ( s + 6 )}

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

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

\frac{( 3 + 4 i ) ^{4}}{( 2 - i ) ^{10}}

\frac{( x + 1 ) ^{2} ( x - 3 )}{( x - 4 ) ^{3} ( x + 5 )}
