Hello!!! Princess Sakura here ^^
Step-by-step explanation:
The answer is choice D. I always remember it by the bigger number is the one that is going to get divided but that doesn't always work out, but in this case it does.
CE = CD + DE = 2DE + DE = 3DE = 8.7
DE = 8.7/3 = 2.9
CD = 2DE = 5.8
For the inscribed circle, where center is point D. The radius is length DE.
This is because the circle will touch the 3 points where the bisectors intersect with sides of triangle.
radius = 2.9
For circumscribed circle, the center will also be point D. The radius is CD.
The circle will touch 3 points of triangle, A,B,C.
radius = 5.8
<span>We have the following polynomial:
The problem states that one root is -3. Thus, it is true that
is a factor of the polynomial. Given that this is fulfilled, it is also true that:

We can find Q(x) by applying Ruffini's rule, thus:

Therefore:
The roots of this polynomial can be get as follows:
These are the roots along with
. Finally, the factored polynomial can be written as follows:
