Question

Arrange the following polynomial into descending order and identify the 3rd term. 18x + 2x3 − 3x2 + 10 (2 points) Select one: a. 18x b. 2x3 c. −3x2 d. 10

Answer 1

18x

Explanation:

The highest power of x is x^3. Note that you must use " ^ " to denote exponentiation. The next highest power is x^2, followed by x and x^0 (=1). Thus, in descending order by power of x, we have 2x^3 - 3x^2 + 18x + 10. Here the third term is 18x.
