Question

Identify the polynomial written in descending order.



4x3 + 12x2 – 5x – 1
–1 – 5x + 12x2 + 4x3
–5x – 1 + 4x3 + 12x2
12x2 + 4x3 – 1 – 5x

Answer 1

Just look at the exponents. It should start with the highest exponent and end with the lowest. So Since 4x^3 is only the written first in the first answer choice, it would be that one!
Good Luck!

Answer 2

4x^3 + 12x^2 – 5x – 1

Answer 3

8x2 + 6x + 1
8x2 – 6x – 7
8x2 + 6x – 1
8x2 – 6x + 7

Answer 4

All of the above are in descending order based on the exponents.

Answer 5

it cant be

Scroll down to "Descending Order"

With regard to polynomials:

"Note that the standard form of a polynomial that is shown above is written in descending order. This means that the term that has the highest degree is written first, the term with the next highest degree is written next, and so forth."

You are dealing with polynomials here, not signed integers.
