Which of the following is a trinomial?
Answer and explanation
Correct answer: \(x^2-2x+1\)
A polynomial containing three unlike terms is called a trinomial. In \(x^2-2x+1\), the three terms are \(x^2\), \(-2x\), and \(1\), so it is a trinomial. Option C has only two terms and is therefore a binomial. Exam tip: count the terms separated by plus or minus signs, treating the sign as part of the term.
