Answer :
Answer:
B. 3x¹¹ +9x⁷ +5x³ −x +4
Step-by-step explanation:
You want to identify the polynomial that has terms written in descending order of their degree.
Degree
The degree of a term is the exponent of x in that term. In the given polynomial, the term degrees are 3, 1, 7, 0, 11.
When these are put into descending order, that order is ...
11, 7, 3, 1, 0
Standard form
The answer to this question will be the polynomial with terms written in the order of their degree as shown above:
3x¹¹ +9x⁷ +5x³ −x +4
__
Additional comment
When the exponent of x is 0, the value of the term x^0 is 1. That is why we can say the constant term is a term that has the variable to degree 0.
