Question

Responses

2x2−9
2 x squared minus 9

3x2+5x−9
3 x squared plus 5 x minus 9

3x2−5x+9
3 x squared minus 5 x plus 9

−2x2+9

Answer 1

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

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

2. Combine 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 response is: 3x²−5x+9
(3 x squared minus 5 x plus 9)
