Which expression has three terms?

Which expression has three terms?

• A. 2x
• B. x^2 + 4x + 1
• C. 5y
• D. 3x + 2

Answer: (B)

This question checks your ability to count terms in an algebraic expression. A term is a single number, variable, or product of numbers and variables that is separated from others by addition or subtraction. The expression x^2 + 4x + 1 has three parts separated by plus signs: x^2, 4x, and 1. Each part is a separate term, so there are three terms. The other expressions are a single term (2x), a single term (5y), or two terms (3x + 2). Therefore, the expression with three terms is x^2 + 4x + 1.
