The problem is to solve the exponential equation algebraically:

\[
e^x = e^{x^2} - 12
\]

### Steps to Solve:

1. **Rearrange the equation:**
   \[
   e^x - e^{x^2} = -12
   \]

2. **Simplify by factoring:**
   This equation doesn't lend itself directly to factoring or logarithmic simplifications due to the \(x^2\) in the exponent. Numerical methods or approximations are more practical for solving such equations.

3. **Use numerical approximation:**
   Since solving this algebraically is impractical, we can use a numerical method like Newton's method or a calculator to find approximate solutions.

### Numerical Solution:

Using numerical methods (e.g., a graphing calculator or software):

- Graph \(y = e^x - e^{x^2} + 12\), and find where \(y = 0\).
- Approximate the solution to three decimal places.

**Solution:**
\[
x \approx 3.018
\]
