hartnn · Answer

since it has 3 different terms,can u guess what it would be? monomial or binomial
or trinomial?
the degree of polynomial is the highest power of any term in it...can u tell me powers of each term?

anonymous · Answer

Question 1 (d)?
Question 2 (a) ?

hartnn · Answer

nopes,3 terms-->trinomial
highest power is for the term 5xy3...1+3=4

anonymous · Answer

haha atfirst i thought it was trinomial as well.. but i thought polynomial is anything more than or equal to power of 2?

anonymous · Answer

http://en.wikipedia.org/wiki/Polynomial wikipedia says it is polynomiall o.O

hartnn · Answer

nopes,trinomial=3 different terms,binomial=2 different terms

hartnn · Answer

yes,its also a polynomial,but more accurate answer would be trinomial

anonymous · Answer

Thanks a lot you guys. @hartnn
