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

Jan 7, 2016

3rd term = $- 9 {f}^{2}$

#### 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 :

$16 {f}^{4} + 4 {f}^{3} - 9 {f}^{2} + 19 f$

$\Rightarrow 3 r d t e r m = - 9 {f}^{2}$
