To simplify the expression \((3x^2 - 2) + (11 - 5x)\), we can combine the like terms step by step:
1. Start by distributing the addition:
\[
3x^2 - 2 + 11 - 5x
\]
2. Combine the constant terms \(-2\) and \(11\):
\[
3x^2 - 5x + (11 - 2) = 3x^2 - 5x + 9
\]
Thus, the simplified expression is:
\[
3x^2 - 5x + 9
\]
So, the correct answer is:
\[
\text{3x}^2 - 5x + 9
\]
