What is the coefficient of x in (x^2 + 3x + 2)?

Answer and explanation

Correct answer: 3

The coefficient of a variable is the numerical factor multiplied by that variable. In the polynomial x² + 3x + 2, the term containing x to the first power is 3x. Since 3x means 3 multiplied by x, the coefficient of x is 3, making option C correct. The number 1 is the understood coefficient of x², not of x. The number 2 is the constant term because it contains no variable. The expression x² is another term with a different power of x, so it cannot be the numerical coefficient of the first-power x term. Identifying the exact requested term avoids confusing coefficients with terms or constants.
