You want the other three roots of P?
If 2+4i is one root then 2-4i is also a root ....
The quadratic factor for these two roots is
Divide P(x) by to find the other two roots.

The rule of this forum is:
EACH POST must go with a question.
The posts without questions are the subject of ignoring.
------------
This is a FORMAL rule.
There is also an informal one. // at least, of the same significance . . .
You posted something and you expect tutors will work for you.
It is your best opportunity to show your respect to tutors and to say "PLEASE . . . ".
Instead, you demonstrate your full disrespect and even do not put your question.
