Yes, you can simplify the expression \(\frac{x^2 - 3}{x + 5}\), but not much more can be done with it unless there are common factors between the numerator and the denominator.

Since the numerator \(x^2 - 3\) does not factor nicely into anything that cancels with \(x + 5\), the expression remains in its current form. Thus, the simplified expression is still:

\[
\frac{x^2 - 3}{x + 5}
\]

This expression is already in its simplest form.

### Here are 5 related questions to consider:
1. What would happen if you had common factors between the numerator and denominator?
2. How would you handle this expression if the numerator were factorable?
3. Can you evaluate this expression for a particular value of \(x\)?
4. How would you graph this rational expression?
5. What are the domain restrictions of this expression?

### Tip:
Always check for common factors when simplifying rational expressions—they may cancel and reduce the expression further.
