The given differential equation is:

\[
\frac{dy}{dx} = y^2 + x^3
\]

This is a first-order non-linear ordinary differential equation. Since it involves both \( y^2 \) and \( x^3 \), standard separation of variables isn't directly applicable, and no exact solution is easily obtainable in elementary functions. However, I can proceed by discussing potential approaches or techniques:

### 1. **Numerical Solution**: 
Since this equation is non-linear, solving it analytically may be difficult, but numerical methods like **Euler's method** or **Runge-Kutta** methods could approximate the solution over a specific interval.

### 2. **Qualitative Analysis**:
We could analyze the behavior of solutions by examining **critical points** and the nature of the differential equation near those points. For example, if \( y = 0 \) is a critical solution for a specific initial condition, the equation becomes:

\[
\frac{dy}{dx} = x^3
\]

which can be integrated directly to find:

\[
y(x) = \frac{x^4}{4} + C
\]

where \( C \) is a constant of integration. 

Would you like to explore any specific method, or should I dive deeper into numerical methods?
