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

expand

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

\frac{s}{s ^{3} - s ^{2} + k ^{2} s - k ^{2}}

Solution steps

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

Expand

(s^{2} + k^{2}) (s - 1) : s^{3} - s^{2} + k^{2} s - k^{2}

= \frac{s}{s ^{3} - s ^{2} + k ^{2} s - k ^{2}}

\frac{x ^{2} + 10 x - 36}{x ( x - 3 ) ^{2}}

(x + 1) (x - 4) (x + \frac{1}{2}) (x - \frac{4}{3})

(w - \frac{5}{7}) (w - \frac{3}{4})

\frac{1}{5} (10 x - 25)
