Question 1186648
.
f(x) is a polynomial function of degree 3 whose coefficients are real numbers; its zeros are 4+i, 4-i, and 2+i.
~~~~~~~~~~~~~~~~~



As described,  such a polynomial  DOES  NOT  exist.


Two roots are conjugated,  but the third root is not a real number.


The third root is a complex number,  which has no conjugate pair to make a polynomial with real coefficients.


This problem is a  FAKE.



In addition,  since a question absents in the post,  it can not be called  "Math problem",  at all.



It is an essay / dream / cry  about a non-existing polynomial, in encrypted form.
