(d^2)/(dx^2)(-2x^4-2x^3+60x^2-22)

解

\frac{d ^{2}}{d x ^{2}} (- 2 x^{4} - 2 x^{3} + 60 x^{2} - 22)

- 24 x^{2} - 12 x + 120

解答ステップ

\frac{d ^{2}}{d x ^{2}} (- 2 x^{4} - 2 x^{3} + 60 x^{2} - 22)

\frac{d}{d x} (- 2 x^{4} - 2 x^{3} + 60 x^{2} - 22) = - 8 x^{3} - 6 x^{2} + 120 x

= \frac{d}{d x} (- 8 x^{3} - 6 x^{2} + 120 x)

\frac{d}{d x} (- 8 x^{3} - 6 x^{2} + 120 x) = - 24 x^{2} - 12 x + 120

= - 24 x^{2} - 12 x + 120
