expand 1/((s+1)^2(s-5))

expand

\frac{1}{( s + 1 ) ^{2} ( s - 5 )}

\frac{1}{s ^{3} - 3 s ^{2} - 9 s - 5}

Solution steps

\frac{1}{( s + 1 ) ^{2} ( s - 5 )}

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

= \frac{1}{( s ^{2} + 2 s + 1 ) ( s - 5 )}

Expand

(s^{2} + 2 s + 1) (s - 5) : s^{3} - 3 s^{2} - 9 s - 5

= \frac{1}{s ^{3} - 3 s ^{2} - 9 s - 5}

2 (3^{n - 1})

\frac{( 6 x - 1 ) ( x + 4 )}{2}

(3 x^{2} - 10 x + 14) d x

(1 - 0.8 e^{- i x})^{2}
