The expression where the \( x \) term has a coefficient of \( -1 \) is:
**3x² - x - 4**
In this expression, the coefficient of the \( x \) term is indeed \( -1 \).
Here's the breakdown:
1. **−2x² + x + 7**: Coefficient of \( x \) is \( +1 \).
2. **3x² − x − 4**: Coefficient of \( x \) is \( -1 \).
3. **2x² + 6x − 1**: Coefficient of \( x \) is \( +6 \).
4. **−x² + 3x + 1**: Coefficient of \( x \) is \( +3 \).
So the correct expression is **3x² − x − 4** where the coefficient of \( x \) is \( -1 \).
