derivative 2x^2+7x^2+4x

解

導関数

2 x^{2} + 7 x^{2} + 4 x

解

18 x + 4

解答ステップ

\frac{d}{d x} (2 x^{2} + 7 x^{2} + 4 x)

簡素化

2 x^{2} + 7 x^{2} + 4 x : 9 x^{2} + 4 x

= \frac{d}{d x} (9 x^{2} + 4 x)

和/差の法則を適用:

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

= \frac{d}{d x} (9 x^{2}) + \frac{d}{d x} (4 x)

\frac{d}{d x} (9 x^{2}) = 18 x

\frac{d}{d x} (4 x) = 4

= 18 x + 4
