expand (2s+1)/(s(s+3)^2)

expand

\frac{2 s + 1}{s ( s + 3 ) ^{2}}

\frac{2 s + 1}{s ^{3} + 6 s ^{2} + 9 s}

Solution steps

\frac{2 s + 1}{s ( s + 3 ) ^{2}}

(s + 3)^{2} = s^{2} + 6 s + 9

= \frac{2 s + 1}{s ( s ^{2} + 6 s + 9 )}

Expand

s (s^{2} + 6 s + 9) : s^{3} + 6 s^{2} + 9 s

= \frac{2 s + 1}{s ^{3} + 6 s ^{2} + 9 s}

(e^{- 3 t} + e^{3 t})^{2}

\frac{z + 0.8}{z ( z - 0.6 ) ( z - 0.9 )}

\frac{2 m ( 4 3 + 5 m )}{5}

\frac{M ( X + 1 )}{3 X + 2}

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