\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
