−2x2+9
negative 2 x squared plus 9

2x2−9
2 x squared minus 9

3x2+5x−9

Answer 1

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

1. Start by distributing and rewriting the expression:
\[
3x^2 - 2 + 11 - 5x
\]

2. Now combine the constant terms and the linear terms:
- The constant terms: \(-2 + 11 = 9\)
- The linear term: \(-5x\) remains as it is.

So, the final expression becomes:
\[
3x^2 - 5x + 9
\]

Thus, the answer is:
**3x² - 5x + 9** (or **3 x squared minus 5 x plus 9**).
