    "The degree of a polynomial is the highest degree of its terms when the polynomial is expressed in its canonical form consisting of a linear combination of monomials. The degree of a term is the \(sum\) of the exponents of the variables that appear in it" (wiki)

    So it is a 2nd degree polynomial being 2 and yes its x^2

    It's not. Please read the definition of the degree of a polynomial, \(and\) the degree of a \(term\).

    It's not because if you look only at the degree of y, then the degree would be 1.

    @mathmate so do i add all of the exponents together making it a 7th dgree polynomial?

    "The degree of a polynomial is the highest degree of its \(terms\), ..." Can you tell me how many terms there are in the given expression?

    So it would be a 3rd degree olynomial

    Good. Can you tell me the degree of each term? Recall "...The degree of a \(term\) is the sum of the exponents of the variables that appear in it"

    Also remember \(xyz\equiv x^1y^1z^1\) to help you add up the exponents.

    4x^2+3xy+12yz 1st term goes to the 2nd degree 2nd term goes to the 2nd degree and 3rd term goes to the second degree so that is a 2nd degree trinomial
