Question

When the expression -3x^5+6x^2-9x^3-x is written with terms in descending order (from highest to lowest), which list represents the coefficients of the term?

a. 6, -9, -3, -1
b. -3, 6, -9, -1
c. 1, 6, -9, -3
d. -3, -9, 6, -1

Answer 1

To write the expression in descending order, we need to arrange the terms based on the exponent of x, from highest to lowest. So the expression can be written as:

-3x^5 - 9x^3 + 6x^2 - x

Now we can see that the coefficients of the terms in descending order are:

-3, -9, 6, -1

Therefore, the correct answer is option d.
