Question 966582
You say, "Degree 4", and then listed the equivalent of THESE zeros:


The Zeros:
3
2-2i
2-2i
-

Since you show that complex number as one of the zeros  (twice according to multiplicity of 2), you must also have  .....


The Zeros:
3
2-2i
2+2i
2-2i
2+2i
Because complex zeros occur in conjugate pairs.


This will not work as degree 4.   This must be degree 5.
