derivative of 3x^2-18x-21

解

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

解

6 x - 18

解答ステップ

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

和/差の法則を適用:

(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

簡素化

= 6 x - 18
