derivative of

y = 1 - 2 x - x^{2}

- 2 x - 2

Solution steps

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

Apply the Sum/Difference Rule:

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

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

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

\frac{d}{d x} (2 x) = 2

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

= 0 - 2 - 2 x

Simplify

= - 2 x - 2

\frac{x ^{3} + 8}{3}

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

\frac{d}{d a} (sec^{2} (a) + cos^{2} (a))

\frac{2}{( x + 3 )}

2 tan (x) + sec (x) - 3 cot (x)
