solve the given initial-value problem

### Differential Equation Solution Example

#### Problem Statement:
Solve the following differential equation with the given initial value:

\[
x y^2 \frac{dy}{dx} = y^3 - x^3, \quad y(1) = 2
\]

### Explanation:
1. **Understanding the equation:**
   - The equation is given in the form \( x y^2 \frac{dy}{dx} = y^3 - x^3 \).
   - This is a first-order, non-linear differential equation.

2. **Initial Condition:**
   - The initial condition provided is \( y(1) = 2 \).
   
3. **Procedure:**
   - To solve this, one might separate variables or use substitution methods, depending on what's most appropriate for the form of the differential equation.

### Detailed Steps:
1. Rewrite the differential equation:
   \[
   x y^2 \frac{dy}{dx} = y^3 - x^3
   \]
   Dividing both sides by \( y^2 \), we get:
   \[
   x \frac{dy}{dx} = y - \frac{x^3}{y^2}
   \]

2. Multiplying both sides by \( dx \) and separating variables, we obtain:
   \[
   \frac{y^2}{y^3 - x^3} dy = \frac{1}{x} dx
   \]

3. Integrate both sides within suitable limits.

### Conclusion:
- After integration, apply the initial condition \( y(1) = 2 \) to find the constant of integration.
- Solve the resulting equation to get the explicit form of \( y \) in terms of \( x \).

Please check an appropriate reference or differential equations resource for the integration steps and final solution. This equation might require more advanced integration techniques or numerical methods for a full solution.
