- 2 x^{4} \frac{d ^{2} y}{d x ^{2}} - 16 x^{3} \frac{d y}{d x} - 24 x^{2} y + 5 x \frac{d ^{2} y}{d x ^{2}} + 10 \frac{d y}{d x} + 2 \frac{d y}{d x}^{2} + 2 y \frac{d ^{2} y}{d x ^{2}}

Schritte zur Lösung

\frac{d ^{2}}{d x ^{2}} ((y) (y - 2 x^{4} + 5 x))

\frac{d}{d x} (y (y - 2 x^{4} + 5 x)) = - 2 x^{4} \frac{d y}{d x} - 8 x^{3} y + 5 x \frac{d y}{d x} + 2 y \frac{d y}{d x} + 5 y

= \frac{d}{d x} (- 2 x^{4} \frac{d y}{d x} - 8 x^{3} y + 5 x \frac{d y}{d x} + 2 y \frac{d y}{d x} + 5 y)

\frac{d}{d x} (- 2 x^{4} \frac{d y}{d x} - 8 x^{3} y + 5 x \frac{d y}{d x} + 2 y \frac{d y}{d x} + 5 y) = - 2 x^{4} \frac{d ^{2} y}{d x ^{2}} - 16 x^{3} \frac{d y}{d x} - 24 x^{2} y + 5 x \frac{d ^{2} y}{d x ^{2}} + 10 \frac{d y}{d x} + 2 \frac{d y}{d x}^{2} + 2 y \frac{d ^{2} y}{d x ^{2}}

= - 2 x^{4} \frac{d ^{2} y}{d x ^{2}} - 16 x^{3} \frac{d y}{d x} - 24 x^{2} y + 5 x \frac{d ^{2} y}{d x ^{2}} + 10 \frac{d y}{d x} + 2 \frac{d y}{d x}^{2} + 2 y \frac{d ^{2} y}{d x ^{2}}
