Answer:
The expression is given below as
A cubic polynomial is a type of polynomial based on the degree i.e. the highest exponent of the variable. Hence, a cubic polynomial is a polynomial with the highest power of the variable or degree is 3.
Hence,
Since the expression has a power with the highest exponent as 3,
The expression represents A CUBIC polynomial with 2 terms
The constant term is
The highest power of the variable that occurs in the polynomial is called the degree of a polynomial. The leading term is the term with the highest power, and its coefficient is called the leading coefficient.
Hence,
The leading term is the term containing that degree
The leading term is given below as
The leading coefficient is the coefficient of that term
The leading coefficient is
