expand s/((s+2)^2(s^2+9))

expand

\frac{s}{( s + 2 ) ^{2} ( s ^{2} + 9 )}

\frac{s}{s ^{4} + 13 s ^{2} + 4 s ^{3} + 36 s + 36}

Solution steps

\frac{s}{( s + 2 ) ^{2} ( s ^{2} + 9 )}

(s + 2)^{2} = s^{2} + 4 s + 4

= \frac{s}{( s ^{2} + 4 s + 4 ) ( s ^{2} + 9 )}

Expand

(s^{2} + 4 s + 4) (s^{2} + 9) : s^{4} + 13 s^{2} + 4 s^{3} + 36 s + 36

= \frac{s}{s ^{4} + 13 s ^{2} + 4 s ^{3} + 36 s + 36}

\frac{25 ( x - 2 )}{58}

(π - x) cos (x)

\frac{3 x ^{2} + 4 x}{2 ( x + 1 ) ^{\frac{3}{2}}}
