Are polynomials determined to be a trinomial, binomial, etc. based on the number of operations or the terms?

For example, would x²y³ + 7y - 35 be determined as a binomial because of the number of operation signs or a trinomial based on the 3 terms?

Respuesta :

Polynomials are determined to be a trinomial, binomial, etc by the amount of terms they have 
For example
7x+3 is a binomial
