"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)
MeowLover17
  • MeowLover17
So it is a 2nd degree polynomial being 2 and yes its x^2
mathmate
  • mathmate
It's not. Please read the definition of the degree of a polynomial, \(and\) the degree of a \(term\).
mathmate
  • mathmate
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?
MeowLover17
  • MeowLover17
I submittedt and got it wrongplease tell me what it is so i can better understand

"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?
MeowLover17
  • MeowLover17
4
MeowLover17
  • MeowLover17
So it would be a 3rd degree olynomial
mathmate
  • mathmate
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"
MeowLover17
  • MeowLover17
Let me show you this one and ill tell you tedegrees of terms let me know f im right please
mathmate
  • mathmate
ok
mathmate

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

  • MeowLover17
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
mathmate
  • mathmate
Exactly! Perfect!
