Answer:

Cubic trinomial

Explanation:

The degree of a term is the sum of the exponents of its variables

  • Quadratic: a polynomial of degree two
  • Cubic: a polynomial of degree three

Therefore, -5x³ - 4x + 1 is a cubic (since the sum of the exponents is 3)

  • monomial: a polynomial with exactly one term
  • binomial: a polynomial with exactly two terms
  • trinomial: a polynomial with exactly three terms

Therefore, -5x³ - 4x + 1 is a trinomial (as it has exactly 3 terms)
