That is a quadratic trinomial.
Its largest degree is 2 (which makes it quadratic), and it has 3 terms separated by addition operators (which makes it trinomial).
By definition, the standard form of a polynomial is given by:

We then have the following polynomial:

Rewriting in its standard form we have:

We realize that the polynomial has three terms, therefore, it is a trinomial.
The largest exponent of the polynomial is three and therefore we have a trinomial of degree three.
Answer:

Three degree trinomial.
