To simplify the expression \( (3x^2 - 2) + (11 - 5x) \), we combine like terms step-by-step:

1. Start with the original expression:
\[
3x^2 - 2 + 11 - 5x
\]

2. Rearrange the terms:
\[
3x^2 - 5x + (-2 + 11)
\]

3. Combine the constant terms:
\[
-2 + 11 = 9
\]

4. Substitute back:
\[
3x^2 - 5x + 9
\]

Thus, the simplified expression is:
\[
3x^2 - 5x + 9
\]

The correct response is:
**3x² - 5x + 9**
