For this case we have given a polynomial of the form:

So:
x: It is the variable
They are the coefficients. Where
is called a constant coefficient (or indendent term), and
is the main coefficient.
n, n-1, n-2,1,0: They are the exponents. where the largest represents the degree of the polynomial.
Answer:
The leading coefficient is

The degree of the polynomial is n
The constant term of the polynomial is
