Which option correctly describes the type of the polynomial \(x^3-1\)?
Answer and explanation
Correct answer: Cubic binomial
The polynomial \(x^3-1\) has two terms, \(x^3\) and \(-1\), so it is a binomial. Its highest exponent is 3, so it is a cubic binomial. Option B is incorrect because the polynomial has neither three terms nor degree 2. Exam tip: classify a polynomial first by its highest degree and then by its number of terms.
