expand (sw)/((s^2+w^2)(s^2+1))

expand

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

\frac{s w}{s ^{4} + s ^{2} + s ^{2} w ^{2} + w ^{2}}

Solution steps

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

Expand

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

= \frac{s w}{s ^{4} + s ^{2} + s ^{2} w ^{2} + w ^{2}}

- \frac{15 ( x - 12 ) ^{2}}{2}

\frac{( x ^{4} - 12 x ^{2} )}{( x ^{2} - 4 ) ^{2}}

\frac{( x + y ) ^{2}}{3}

\frac{x s ^{2} + 5 s + 7}{( s ^{2} + 2 ) ( s + 1 )}

\frac{6 ( 168 x ^{3} - 140 x ^{2} + 30 x - 1 )}{x ^{\frac{1}{2}}}
