expand 1/(s^2(s^2+ω^2))

expand

\frac{1}{s ^{2} ( s ^{2} + ω ^{2} )}

\frac{1}{s ^{4} + ω ^{2} s ^{2}}

Solution steps

\frac{1}{s ^{2} ( s ^{2} + ω ^{2} )}

Expand

s^{2} (s^{2} + ω^{2}) : s^{4} + ω^{2} s^{2}

= \frac{1}{s ^{4} + ω ^{2} s ^{2}}

\frac{x}{( 3 x ^{2} - 1 ) ^{2}}

\frac{( x ^{4} - 1 ) ^{2}}{x ^{4}}

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