Which polynomial is written in descending order?

9 _ 3x + 4x2

_3x + 9 + 4x2

4x2 _ 3x + 9

4x2 + 9 _ 3x

The ascending or descending order of a polynomial is determined by the increasing or decreasing power of variable “x” respectively.

The question is to find about the polynomial in descending order, so in this case, the 3rd option is correct, i.e. 4x^2 – 3x + 9 or 4x^2 – 3x^1 +9x^0. The power of “x” decreasing from 2 to 1 and then finally to 0.

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

answer: none of these answers are correct only the second half is
