1 answer

To simplify the expression \((3x^2 - 2) + (11 - 5x)\), we can combine like terms. Here's how to do that step by step:

  1. Write down the expression: \[ 3x^2 - 2 + 11 - 5x \]

  2. Combine the constant terms \(-2\) and \(11\): \[ -2 + 11 = 9 \]

  3. Now, rewrite the expression: \[ 3x^2 - 5x + 9 \]

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

The correct answer is: 3x^2 - 5x + 9
