The degree is the highest exponent in a term, the term with the highest exponent is -m^4, so the degree is 4. Terms are separated by operation signs such as +, -, ×, ÷. So the number of terms here are 3.

1 term = Monomial
 
2 terms = Bionomial

3 terms = Trinomial

4+ terms = Polynomial

So this is a 4th degree trinomial.

\(1 term = Monomial\)

\(2 terms = Bionomial\)

\(3 terms = Trinomial\)

\(4+ terms = Polynomial\)


So this is a 4th degree trinomial.
