What is the 3rd term when 5 + 3x² - 5x⁴ + 2x³ is arranged in descending order?

Solution:

The given equation is

5 + 3x² - 5x⁴ + 2x³

We have to arrange it in descending order

= - 5x⁴ + 2x³ + 3x² + 5

Therefore, the 3rd term is 3x².

Example -

What is the 2nd term when 8 + 2x² + 3x⁴ + 4x³ is arranged in descending order?

Solution:

The given equation is

8 + 2x² + 3x⁴ + 4x³

We have to arrange it in descending order

= 3x⁴ + 4x³ + 2x² + 8

Therefore, the 2nd term is 4x³.
