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.
