\frac{d}{d x} (3 x^{2} - 18 x - 21)

6 x - 18

Solution steps

\frac{d}{d x} (3 x^{2} - 18 x - 21)

Apply the Sum/Difference Rule:

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

= \frac{d}{d x} (3 x^{2}) - \frac{d}{d x} (18 x) - \frac{d}{d x} (21)

\frac{d}{d x} (3 x^{2}) = 6 x

\frac{d}{d x} (18 x) = 18

\frac{d}{d x} (21) = 0

= 6 x - 18 - 0

Simplify

= 6 x - 18

\int e^{- t^{2}} t d t

\int cos (x) (sin (x))^{5} d x

\int e^{- \frac{5 x}{6}} d x

n = 1 \sum \infty 7 (0.9)^{n - 1}

f (x) = (3 x^{2} + 1)^{3}
