Which is the correct identification of (2x^3-5x+4)?

Answer and explanation

Correct answer: Cubic trinomial polynomial

In the polynomial \(2x^3-5x+4\), the highest power of \(x\) is \(3\), so it is a cubic polynomial. It has three terms: \(2x^3\), \(-5x\), and \(4\); therefore, it is a trinomial. Hence, it is a cubic trinomial polynomial. A linear polynomial has highest degree 1. Exam tip: first find the highest exponent, then count the terms to classify a polynomial.
