expand (2s^2+10)/((s^2+4)(s^2-4))

expand

\frac{2 s ^{2} + 10}{( s ^{2} + 4 ) ( s ^{2} - 4 )}

\frac{2 s ^{2} + 10}{s ^{4} - 16}

Solution steps

\frac{2 s ^{2} + 10}{( s ^{2} + 4 ) ( s ^{2} - 4 )}

Expand

(s^{2} + 4) (s^{2} - 4) : s^{4} - 16

= \frac{2 s ^{2} + 10}{s ^{4} - 16}

(\frac{1}{5} - x) (\frac{2}{5} - x)

(2 x + 5) (x + 5) (x - 5)

(x + 1 + 12 - x)^{2}

(- 3 + \frac{3}{x ^{5}}) (x^{4} + 5)

9 - x (x^{4} + x^{3} + x^{2} + x + 1)
