derivative (x^2-2x-8)/(x+2)

解

導関数

\frac{x ^{2} - 2 x - 8}{x + 2}

解

1

解答ステップ

\frac{d}{d x} (\frac{x ^{2} - 2 x - 8}{x + 2})

簡素化

\frac{x ^{2} - 2 x - 8}{x + 2} : x - 4

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

和/差の法則を適用:

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

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

\frac{d x}{d x} = 1

\frac{d}{d x} (4) = 0

= 1 - 0

簡素化

= 1
