Question

Which description is correct for the polynomial -5x^3-4x+1?

Answer 1

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)
