The correct Answer is:
To solve the problem, we need to analyze the given statements and derive the corresponding differential equation from the general solution provided. ### Step-by-Step Solution: 1. **Identify the General Solution**: The general solution given is: \[ y = c_1 x + \frac{c_2}{x} \] Here, \(c_1\) and \(c_2\) are arbitrary constants. 2. **Differentiate the General Solution**: We differentiate \(y\) with respect to \(x\): \[ \frac{dy}{dx} = c_1 - \frac{c_2}{x^2} \] 3. **Differentiate Again**: We differentiate \(\frac{dy}{dx}\) to find the second derivative: \[ \frac{d^2y}{dx^2} = 0 + \frac{2c_2}{x^3} \] This simplifies to: \[ \frac{d^2y}{dx^2} = \frac{2c_2}{x^3} \] 4. **Express \(c_2\) in terms of \(\frac{d^2y}{dx^2}\)**: Rearranging the equation gives: \[ c_2 = \frac{x^3}{2} \frac{d^2y}{dx^2} \] 5. **Substitute \(c_2\) back into the first derivative**: We can express \(c_1\) using the first derivative: \[ c_1 = \frac{dy}{dx} + \frac{c_2}{x^2} \] Substituting for \(c_2\): \[ c_1 = \frac{dy}{dx} + \frac{\frac{x^3}{2} \frac{d^2y}{dx^2}}{x^2} \] Simplifying gives: \[ c_1 = \frac{dy}{dx} + \frac{x}{2} \frac{d^2y}{dx^2} \] 6. **Substituting \(c_1\) and \(c_2\) back into the original equation**: Substitute \(c_1\) and \(c_2\) back into the general solution: \[ y = \left(\frac{dy}{dx} + \frac{x}{2} \frac{d^2y}{dx^2}\right)x + \frac{\frac{x^3}{2} \frac{d^2y}{dx^2}}{x} \] This simplifies to: \[ y = x \frac{dy}{dx} + \frac{x^2}{2} \frac{d^2y}{dx^2} + \frac{x^2}{2} \frac{d^2y}{dx^2} \] Combining terms results in: \[ y = x \frac{dy}{dx} + x^2 \frac{d^2y}{dx^2} \] 7. **Final Form of the Differential Equation**: The resulting differential equation is: \[ y - x \frac{dy}{dx} - x^2 \frac{d^2y}{dx^2} = 0 \] 8. **Determine the Order of the Differential Equation**: The highest derivative present is \(\frac{d^2y}{dx^2}\), indicating that this is a second-order differential equation. ### Conclusion: - **Statement 1** is true: The differential equation whose general solution is \(y = c_1 x + \frac{c_2}{x}\) is indeed a linear equation. - **Statement 2** is also true: The equation has two arbitrary constants, thus the corresponding differential equation is of second order.
