Question

What is (3x2−2)+(11−5x) ?(1 point) Responses 3x2+5x−9 3 x squared plus 5 x minus 9 −2x2+9 negative 2 x squared plus 9 3x2−5x+9 3 x squared minus 5 x plus 9 2x2−9

Answer 1

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

1. Combine the \(x^2\) terms: \(3x^2\)
2. Combine the \(x\) terms: \(0 - 5x = -5x\)
3. Combine the constant terms: \(-2 + 11 = 9\)

Putting it all together, we have:

\[
3x^2 - 5x + 9
\]

So, the simplified expression is \(3x^2 - 5x + 9\). The correct response is:

**3x² − 5x + 9**.
