Answer:
yes
Step-by-step explanation:
Answer:
The complex number
has Cartesian form
.
Step-by-step explanation:
First, we need to recall the definition of
when
is a complex number:
.
Then,
. (I)
Now, recall the definition of the complex exponential:
.
So,

(we use that
.
Thus,

Now we group conveniently in the above expression:
.
Now, substituting this equality in (I) we get
.
Thus,

.
Answer:
(x-8) is the factor.
Step-by-step explanation:
The given trinomial is
.
We need to find the factor of this trinomial.

The factors of
is (x-2) and (x-8).
So, the factor of
is (x-8). Hence, the correct option is (B).
