expand derivative of (x-1*(x+1))-2/(x^3)

expand

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

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

Solution steps

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

Expand

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

= \frac{d}{d x} (x^{2} - 1) - \frac{2}{x ^{3}}

sin (2) (x - π)

(x + 25)^{2}

- cos (4) (x + \frac{π}{2}) - 3

(1 - 1 + x) \cdot (x)
