To simplify the expression \((3x^2 - 2) + (11 - 5x)\), follow these steps:
1. Distribute and recombine like terms:
\[
3x^2 - 2 + 11 - 5x
\]
2. Combine the constant terms:
\[
-2 + 11 = 9
\]
3. Now put everything together:
\[
3x^2 - 5x + 9
\]
So the final simplified expression is:
\[
3x^2 - 5x + 9
\]
Thus, the correct response is:
**3x²−5x+9**.
