3x2−5x+9
3 x squared minus 5 x plus 9

−2x2+9
negative 2 x squared plus 9

2x2−9

Answer 1

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

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

2. Distribute: \[ 3x^2 - 2 + 11 - 5x \]

3. Combine the constant terms \(-2\) and \(11\): \[ 3x^2 - 5x + 9 \]

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

The correct response is: 3x²−5x+9 (3 x squared minus 5 x plus 9)
