Question

What is (3x^2 - 2) + (11 - 5x)?

3x^2 - 5x +9
3x^2 + 5x - 9
2x^2 - 9
-2x^2 + 9

Answer 1

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**
