Question

Four polynomials are shown below:

Answer 1

Answer:

Polynomial D

Step-by-step explanation:

D. 3x3 − 5 + 2x5 + x + 2x2

Answer 2

The degree of a polynomial is the value of the highest exponent a variable is raised to (i.e., the degree of the equation $y=x^{2}$ is 2, since the highest exponent of a variable is 2. 

If we apply this concept to your list of polynomials, we see that polynomial A and polynomial D both have $x^{5}$ terms, so they are both fifth-degree polynomials. However, your answer must also be a trinomial (a polynomial with three terms.) If we look at polynomials A and D, we see that only polynomial A has three terms, so that must be the answer!
