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

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

Solution steps

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

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

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

\frac{d}{d x} (1) = 0

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

= 0 - (- \frac{x}{1 - x ^{2}})

Simplify

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