Answer 1

Answer

a. ii and iii

Step-by-step explanation

A monomial is a polynomial with only one term.

A binomial is a polynomial with two terms.

The degree of a polynomial is determined by the highest exponent of the x-variable.

i) 2x² + 2x

type: binomial

degree: 2

ii) 2x²

type: monomial

degree: 2

iii) x²

type: monomial

degree: 2

iv) 2x

type: monomial

degree: 1

Then, choices ii and iii are monomials with degree 2
