Answer:
Cubic trinomial
Step-by-step 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)
