So for part of the question, we are asked to write this expression with the exponents on x in descending order.
00:09
So descending order means we have highest to lowest.
00:14
So highest and then we have lowest.
00:17
So we're going to look at the highest power on x first.
00:20
And then we're going to go from there.
00:21
So this is the highest, right? this negative 2x of power of 4.
00:25
So it's going to start with negative 2x of power of 4.
00:28
Now the next highest degree is going to be minus 5x squared.
00:34
Then we have plus 3x, right? the third highest degree and then plus 7.
00:38
So 7 is just a constant.
00:40
So that's how it's going to work.
00:42
For the second part of the question, we are asked for ascending order.
00:45
Now, ascending order is the opposite of what we just did.
00:49
It's lowest to highest...
