expand (s^2-1)/(s^2(s^2+2))

expand

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

\frac{s ^{2} - 1}{s ^{4} + 2 s ^{2}}

Solution steps

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

Expand

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

= \frac{s ^{2} - 1}{s ^{4} + 2 s ^{2}}

, (2 + \frac{2}{7}) (1 + \frac{1}{6}) (2 + \frac{2}{3}) \cdot \frac{1}{8}

cos (x + y) (1 + y^{'} (x))

(2 z - 6 w (z) = 0,) (- z + 2 w (z) = - 8)

\frac{( 49 s ^{2} + 2 ( 7 s + 1 ) )}{s ^{3}}

\frac{5}{( s + 3 ) ^{2} ( s + 1 )}
