term, or linear term, have a coefficient of −1
?(1 point)
Responses

2x2+6x−1
2 x squared plus 6 x minus 1

3x2−x−4
3 x squared minus x minus 4

−x2+3x+1
negative x squared plus 3 x plus 1

−2x2+x+7

Answer 1

To determine which expression has a coefficient of \(-1\) for the linear term (the \(x\) term), we will look at each option:

1. \(2x^2 + 6x - 1\): The coefficient of \(x\) is \(6\).
2. \(3x^2 - x - 4\): The coefficient of \(x\) is \(-1\).
3. \(-x^2 + 3x + 1\): The coefficient of \(x\) is \(3\).
4. \(-2x^2 + x + 7\): The coefficient of \(x\) is \(1\).

The expression with a linear term coefficient of \(-1\) is:

**\(3x^2 - x - 4\)**.
