Answer 1

Answer:

fourth degree trinomial.

Step-by-step explanation:

we have

$7x^{4}-5x+4$

Classify the polynomial

Remember that

Polynomials can be classified two different ways - by the number of terms and by their degree

1. Number of terms.

In this problem we have tree terms . so is a trinomial

2. Degree.

The degree of the polynomial is found by looking at the term with the highest exponent on its variable(s).

In this problem the highest exponent is the $4$ so this is a fourth degree trinomial.

Answer 2

Fourth-degree trinomial
