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

expand

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

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

Solution steps

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

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

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

Expand

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

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

(- 3 x^{2} + 4 x) e^{5 x}

2 (n ln (n) - n)

\frac{1}{( s ^{2} ( s ^{2} + w ^{2} ) )}

(e^{x} + 1) (12 x - 4)

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