Question

Match the expression with its name.

7x^4 – 5x + 4

cubic binomial
quadratic monomial
fourth-degree trinomial
not a polynomial

Answer 1

fourth-degree trinomial

Answer 2

fourth degree trinomial.

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.
