expand ((s-1)(s+3))/(s(s+4)(s+2))

expand

\frac{( s - 1 ) ( s + 3 )}{s ( s + 4 ) ( s + 2 )}

\frac{s ^{2} + 2 s - 3}{s ^{3} + 6 s ^{2} + 8 s}

Solution steps

\frac{( s - 1 ) ( s + 3 )}{s ( s + 4 ) ( s + 2 )}

Expand

s (s + 4) (s + 2) : s^{3} + 6 s^{2} + 8 s

= \frac{( s - 1 ) ( s + 3 )}{s ^{3} + 6 s ^{2} + 8 s}

Expand

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

= \frac{s ^{2} + 2 s - 3}{s ^{3} + 6 s ^{2} + 8 s}

\frac{d}{d x} ((x - 2) (x - 10)^{3}) + 11
