expand (k(s+4))/(s(s+1)(s+3))

expand

\frac{k ( s + 4 )}{s ( s + 1 ) ( s + 3 )}

\frac{k s + 4 k}{s ^{3} + 4 s ^{2} + 3 s}

Solution steps

\frac{k ( s + 4 )}{s ( s + 1 ) ( s + 3 )}

Expand

s (s + 1) (s + 3) : s^{3} + 4 s^{2} + 3 s

= \frac{k ( s + 4 )}{s ^{3} + 4 s ^{2} + 3 s}

Expand

k (s + 4) : k s + 4 k

= \frac{k s + 4 k}{s ^{3} + 4 s ^{2} + 3 s}

(2 - x - 4)^{2}

- e^{x} (e^{2 x} - e^{- x})

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

(3 sin^{2} (θ)) (1 + sin^{2} (θ))

3 (ln (- 1) + 1)
