expand s/((s^2+4)(s^2+9))

expand

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

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

Solution steps

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

Expand

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

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

x^{4} e^{x} - 4 (x^{3} e^{x} - 3 (x^{2} e^{x} - 2 (e^{x} x - e^{x})))

(\frac{x ^{3}}{6} + \frac{1}{2 x}) (\frac{x ^{2}}{2} + \frac{1}{2 x ^{2}})

(2 cos (x) + 1) (cos (x) - 1)

A (1, 4) N (- 3, - 2)

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