What type of polynomial is this?
2 - 5x^3 + 6x
A)not a polynomial
B)cubic trinomial
C)quadric trinomial
D)fourth-degree trinomial
Since the degree is 4, I think the answer is D. Is this correct?
Wait, nevermind my previous answer...is it B?
yes
Actually, the polynomial 2 - 5x^3 + 6x is a third-degree polynomial, also called a cubic polynomial. The term "cubic" signifies that the highest exponent in the polynomial is 3, which is the case in this example.
To determine the degree of a polynomial, you examine the term with the highest exponent. In this case, the highest exponent is 3, as indicated by the term -5x^3. Therefore, the correct answer is B) cubic trinomial.
