expand (x^2-9)/(x(x^2+1))

expand

\frac{x ^{2} - 9}{x ( x ^{2} + 1 )}

\frac{x ^{2} - 9}{x ^{3} + x}

Solution steps

\frac{x ^{2} - 9}{x ( x ^{2} + 1 )}

Expand

x (x^{2} + 1) : x^{3} + x

= \frac{x ^{2} - 9}{x ^{3} + x}

(z^{2} (a) + z (b) + c) \cdot (z^{2} (d) + z (e) + f)

(x + \frac{10}{3}) (x + 10)

6 \cdot (- 2 + 2 x) \cdot (6 + t) \cdot (t^{2})

2 sin (π t) (u_{4} (t) - u_{5} (t))

1 + \frac{( s + 2.7035 ) ( s + 4 )}{s ^{3} + 2 s ^{2} + 3 s}
