I don’t get this one

It is a Quintic Polynomial

Step-by-step explanation:

When classifying polynomials, there is usually a list that you should get that makes classifying easier.

I put the list down below.

In order to find if it is constant (0), linear (1), quadratic (2), cubic (3), quartic (4), or quintic (5), look at the exponent with the highest value (0 through 5), and it will give you the name. So in the equation, you have above, the highest exponent is 5. So this is a quintic.  

In order to find the next part of the expression, monomial, binomial, trinomial, and polynomial, look at how many terms there are in the expression. There are 4 terms, so this a polynomial.

step-by-step explanation:

infinity is the answer

it should be a.
