Answer:
D.
Step-by-step explanation:
A trinomial expression is a polynomial expression with three terms.
The term with the highest power of variable is called the leading term and the co-efficient of this term is called the leading co-efficient.
The alone number without any variable in the expression is called the constant.
Example of a trinomial:
Leading co-efficient = 5
Constant = 4
A trinomial with a leading coefficient of 3 and a constant term of -5 from the given choices is:
