Answer:
leading coefficient is 8
degree of the leading term is 4
degree of the polynomial is 4
Step-by-step explanation:
Given

Solving (a): The leading coefficient
This is the coefficient of the
with the highest power.
The highest
in the
is 5.
Hence, the leading coefficient is 8
Solving (b): Degree of the leading term
First, we identify the
term, i.e. the term that has the
.
This term is: 
So, the degree of the leading term is 4
Solving (c): Degree of the polynomial
This is the same as the
of the
term
So, the
of the
is 4
