#### Answer

Standard form: $-x^4+3x^2$ Degree = 4 Number of terms = 2 This polynomial is a quartic binomial.

#### Work Step by Step

RECALL: A polynomial is written in standard form if its terms are written in descending degree. Combine like terms in the given expression then arrange the terms in descending degree order to have $-x^4+2x^2+x^2 \\=-x^4+(2+1)(x^2) \\=-x^4+3x^2$. This polynomial has degree 4 and has two terms. It is a quartic binomial.
