Question

Quizplus · Accepted Answer

The powers of x in the options are 9, 8, 7, and 6 respectively. The highest power of x is 9 in option D, so it should come first in descending order. The given expression contains only one variable x. In order to arrange in descending powers of x, we need to rewrite the expression as a polynomial in x. However, the given expression does not give any information about the degree of the polynomial, so we cannot determine the exact order of the terms. However, we can still compare the powers of x by counting the number of "c5", "c6", "c7", and "c8" terms in each option. The option with the highest power of x will have the most number of "c9" terms, followed by "c8", "c7", and "c6" terms. Therefore, option D has the highest power of x, followed by C, B, and A.
