Question

What is the 2nd term when -3f3 + 9f + 6f4 - 2f2 is arranged in descending order?

Answer 1

A polynomial with its terms simplified and written so that the powers of the variables are in order from largest to smallest is said to be in descending order.

Answer 2

Arrange the terms of 3f3 + 9f + 6f4 - 2f2 so that the terms containing the largest power of f is first, then the term containing the second highest power of f next, and continue in that manner.

It looks as if 9f will be the last term of your polynomial when you write it in descending order. @Lalala0726
