expand (s^2-a^2)/((s^2+a^2)^2)

expand

\frac{s ^{2} - a ^{2}}{( s ^{2} + a ^{2} ) ^{2}}

\frac{s ^{2} - a ^{2}}{s ^{4} + 2 a ^{2} s ^{2} + a ^{4}}

Solution steps

\frac{s ^{2} - a ^{2}}{( s ^{2} + a ^{2} ) ^{2}}

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

= \frac{s ^{2} - a ^{2}}{s ^{4} + 2 a ^{2} s ^{2} + a ^{4}}

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

(\frac{15}{s + 1} + 35 s - 21) (s^{2} + 3)

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

(- 1 + e^{- \frac{x}{Bw}}) (e^{- \frac{1}{A}} - 1)

7 cos (x^{3} - 2 x) (3 x^{2} - 2)
