which represents the coefficient from the expression given?

Question

2x-20+x^2

20
2
x^2
x

Answer 1

In the expression \(2x - 20 + x^2\), we can identify the coefficients of each term:

• The term \(2x\) has a coefficient of \(2\).
• The term \(-20\) is a constant and does not have a variable coefficient.
• The term \(x^2\) has a coefficient of \(1\) (as it can be understood as \(1 \cdot x^2\)).

Among the given options:

• 20 is not a coefficient of any variable term.
• 2 is indeed the coefficient of the \(x\) term.
• \(x^2\) is a term and not a coefficient.
• \(x\) is a variable and not a coefficient.

Thus, the correct answer is:

2
