In which of the following expressions does the "x" term have a coefficient of 1?
Responses
2x2−2x−1
2 x squared minus 2 x minus 1
3x2+x−8
3 x squared plus x minus 8
x2+3x+4
x squared plus 3 x plus 4
2x2−x+1
2x2−x+1
The expression where the "x" term has a coefficient of 1 is:
x2 + 3x + 4
To determine which of the given expressions has the "x" term with a coefficient of 1, we need to look at the coefficient directly in front of the "x" term. Let's break down each expression:
1. 2x^2 - 2x - 1:
The coefficient of the "x" term is -2, not 1.
2. 3x^2 + x - 8:
The coefficient of the "x" term is 1, which matches the requirement.
3. x^2 + 3x + 4:
The coefficient of the "x" term is 3, not 1.
4. 2x^2 - x + 1:
The coefficient of the "x" term is -1, not 1.
Therefore, the expression with the "x" term having a coefficient of 1 is 3x^2 + x - 8.
