expand (x^3)/((x^2+1)(s+1)(s-1))

expand

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

\frac{x ^{3}}{x ^{2} s ^{2} - x ^{2} + s ^{2} - 1}

Solution steps

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

Expand

(x^{2} + 1) (s + 1) (s - 1) : x^{2} s^{2} - x^{2} + s^{2} - 1

= \frac{x ^{3}}{x ^{2} s ^{2} - x ^{2} + s ^{2} - 1}

(- 2 ry cos (t) - z sin (t) - x y cos (t))^{2}

\frac{4 ( k + 1 ) ^{3}}{k}

5 (tan (x) + x sec^{2} (x))

- 2 (ln (e^{2} - 12) - 4)

\frac{1}{( ( s ^{2} + 1 ) ( s - 3 ) ( s - 6 ) )}
