Question

Hello. Trying to see where I went wrong on a quiz. How do you do the problem? 

**Problem Statement:**

Solve the initial value problem.

\[
\frac{dy}{dx} = \frac{1}{x^3} + x, \quad x > 0; \quad y(2) = 0
\]

**Multiple Choice Answers:**

1. \( y = -\frac{1}{2x^2} + \frac{x^2}{2} \)

2. \( y = \frac{4}{x^4} + \frac{x^2}{2} - \frac{9}{4} \)

3. \( y = -\frac{1}{2x^2} + \frac{x^2}{2} - \frac{15}{8} \) (Correct Answer)

4. \( y = -\frac{1}{2x^2} + \frac{1}{8} \) (You Answered)

**Explanation:**

The task is to solve the differential equation subject to the initial condition provided. Among the options provided, the correct answer is indicated as the third choice:

\[ y = -\frac{1}{2x^2} + \frac{x^2}{2} - \frac{15}{8} \]

This solution satisfies both the differential equation and the initial condition. The fourth option was the user's answer but was incorrect.
