How many terms are there in the polynomial \(3x^2+2x-1\)?
Answer and explanation
Correct answer: 3
The terms of this polynomial are \(3x^2\), \(2x\), and \(-1\), so it has 3 terms. Terms are identified by separating the expression at plus or minus signs. Counting only \(3x^2\) and \(2x\) gives 2, but the constant term \(-1\) is also a separate term. Exam tip: Count negative terms as well as positive terms.
