expand (5s^3-s^2+2s+5)/(s^2(s^2+9))

expand

\frac{5 s ^{3} - s ^{2} + 2 s + 5}{s ^{2} ( s ^{2} + 9 )}

\frac{5 s ^{3} - s ^{2} + 2 s + 5}{s ^{4} + 9 s ^{2}}

Solution steps

\frac{5 s ^{3} - s ^{2} + 2 s + 5}{s ^{2} ( s ^{2} + 9 )}

Expand

s^{2} (s^{2} + 9) : s^{4} + 9 s^{2}

= \frac{5 s ^{3} - s ^{2} + 2 s + 5}{s ^{4} + 9 s ^{2}}

- w r t (1 - y) (1 - e)

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

2 w (13 w + \frac{168}{w ^{2}})

\frac{4}{x ( x ^{2} + 5 )}
