expand-(1000)/((s-1)(s+1)(s+20))

expand

- \frac{1000}{( s - 1 ) ( s + 1 ) ( s + 20 )}

- \frac{1000}{s ^{3} + 20 s ^{2} - s - 20}

Solution steps

- \frac{1000}{( s - 1 ) ( s + 1 ) ( s + 20 )}

Expand

(s - 1) (s + 1) (s + 20) : s^{3} + 20 s^{2} - s - 20

= - \frac{1000}{s ^{3} + 20 s ^{2} - s - 20}

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

(3.6 \cdot t^{'} + 15)^{2}

\frac{5 s + 2}{( s ) ( s ^{2} + 4 s + 13 )}

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

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