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

expand

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

\frac{s ^{2} - 4}{s ^{4} + 8 s ^{2} + 16}

Solution steps

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

(s^{2} + 4)^{2} = s^{4} + 8 s^{2} + 16

= \frac{s ^{2} - 4}{s ^{4} + 8 s ^{2} + 16}

(- 2 x + 3) (3 x^{2} + 5 x - 1)^{'}

\frac{( t - 3 ) ^{4}}{4}

2 (3 - x^{2} y) d y

\frac{x ^{m + 2} + ( 2 m - 1 ) x + m}{x - 1}

((x - 3) (x - 5) (x - 6)) \cdot 2
