| Mar 2, 2012 at 20:16 | comment | added | Qiuryaq | I edited my question to make it more clear. The situation is I know it factors but don't know what the factorization is. All I want to know is whether the factorization is in real or complex. | |

| Mar 2, 2012 at 16:45 | comment | added | Robert Bryant | Test in terms of what criteria? If you have the 4 factors, can't you just check to see whether the ratios of the coefficients in each factor are real? If so, then each factor is a complex multiple of a real linear form. This is necessary and sufficient. Since this answer is so easy, I suspect that you must have some other restrictions in mind on what you can test. | |
