Descending order involves the exponents of x. In descending order the exponents of x decrease
as you read from left to right.
.
The following is an example of the descending order of x:
.

.
Of course the exponents could be bigger than the 5 I started with. And each of the terms
in this descending order may have a multiplier associated with it ... for example, the series
of terms
.

.
is arranged in descending powers of x. Some of the multipliers could be zero, and that
would cause that power of x to disappear.
.
One thing to note. What is ? Remember the rule that says anything raised to
a zero power is equal to 1. So . And also remember the rule that says
anything raised to the first power is itself. So .
.
Now back to your problem you are given and asked to arrange it in descending
powers of x.
.
Note that . And note that
.
Therefore, the answer to your problem is that in descending powers of x, the numbers
are:
.

.
and the minus x is to the first power, and the +8 is to the zero power. Therefore,
the highest exponent involved is 1 and this makes it a first degree or first order binomial.
.
Hope this is what you were looking for.
