#### Answer

Standard form: $-3x^5+3x^2-1$
Degree = 5
Number of terms = 3
This polynomial is a quintic trinomial.

#### Work Step by Step

RECALL:
A polynomial is written in standard form if its terms are arranged in descending degree.
Simplify the given expression and write the polynomial in standard form:
$-3x^5+2x^2+x^2-1
\\=-3x^5+3x^2-1.$
This polynomial has a degree of 5 and it has three terms.
Thus, it is a quintic trinomial.
