Real … WebOct 21, 2024 · Add a comment. 1. You actually have two zeroes: 2 + 3 i and 2 − 3 i because complex zeros always come in a pair of complex conjugates. Which means, you now have: [ x − ( 2 − 3 i)] [ x − ( 2 + 3 i)] Expand this you get. ( x 2 − 4 x + 13) Then use this as a divisor to your original polynomial.
