Question

What is the 3rd term when `4f^3 + 19f + 16f^4 - 9f^2` is arranged in descending order?

Answer 1

3rd term = `- 9f^2`

Explanation:

To arrange the expression in descending order means writing the expression starting with the highest power , then the next highest etc. until you reach the lowest. If there was a constant term then it would be the lowest but there is not one here.

rewriting the expression in descending order :

`16f^4 + 4f^3 - 9f^2 + 19f`

`rArr 3rd term = -9f^2`
