Answer: Degree of polynomial (highest degree) =4
Maximum possible terms =9
Number of terms in the product = 5
Step-by-step explanation:
A trinomial is a polynomial with 3 terms.
The given product of trinomial: 
By using distributive property: a(b+c+d)= ab+ac+ad

Maximum possible terms =9
Combine like terms

Hence, 
Degree of polynomial (highest degree) =4
Number of terms = 5
