Question 825735
I just did this problem for another poster. But that problem included a given root: 3 + i. The problem is, IMHO, not solvable unless they give you one of the roots because, as you found, none the possible rational roots are actual roots.<br>

P.S. f(x) is <u>not</u> a rational function. So you posted this in the wrong category. "Polynomials" is the correct category for this problem. In the future, post your problems in an appropriate category. It will get a faster response.
