expand (s^2-25)/((s^2+25)^2)

expand

\frac{s ^{2} - 25}{( s ^{2} + 25 ) ^{2}}

\frac{s ^{2} - 25}{s ^{4} + 50 s ^{2} + 625}

Solution steps

\frac{s ^{2} - 25}{( s ^{2} + 25 ) ^{2}}

(s^{2} + 25)^{2} = s^{4} + 50 s^{2} + 625

= \frac{s ^{2} - 25}{s ^{4} + 50 s ^{2} + 625}

\frac{5 ( k + 1 ) ( k + 2 )}{2}

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

\frac{x \cdot ( x - 1 ) \cdot ( x - 2 )}{6}

(2 \cdot (- 3) y = - 1,) (k x + (k - 1) y - 2 (k + 2) = 0,)

\frac{5 x ^{2} - 26 x + 21}{( - x + 5 ) ( - x + 3 )}
