(i) A coefficient is a multiplicative factor in some term of a polynomial. It is the constant (-6 here) written before the variable (x5 here).
∴ The coefficient of x5 is -6.
(ii) Degree of p(x) is the highest power of x in p(x).
∴ The degree of p(x) is 7.
(iii) The term that is not attached to a variable (i.e., x) is -6.
∴ The constant term is -6.
