If y2 + xy + x2 – 2x = 0 then d2y⁄dx2 =? |
| A. | \((2y+x) \frac{d^2 y}{dx^2}+(\frac{dy}{dx})^2+2 \frac{dy}{dx}+2=0\) |
| B. | \((2y+x) \frac{d^2 y}{dx^2}+2(\frac{dy}{dx})^2+\frac{dy}{dx}+2=0\) |
| C. | \((2y+x) \frac{d^2 y}{dx^2}+2(\frac{dy}{dx})^2+2 \frac{dy}{dx}+2=0\) |
| D. | \(x \frac{d^2 y}{dx^2}+2(\frac{dy}{dx})^2+2 \frac{dy}{dx}+2=0\) |
| Answer» D. \(x \frac{d^2 y}{dx^2}+2(\frac{dy}{dx})^2+2 \frac{dy}{dx}+2=0\) | |
