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