Which of the following polynomials is a trinomial?
Answer and explanation
Correct answer: \(x^2+x+1\)
A trinomial is a polynomial containing three unlike terms. In \(x^2+x+1\), the three terms are \(x^2\), \(x\), and \(1\), so it is a trinomial. Option B is a binomial, option C is a monomial, and option D is a four-term polynomial. Exam tip: count the terms separated by plus or minus signs.
