Answer:
There is another complex zero which is a conjugate of the known complex zero.
Explanation:
A quadratic equation s a 2nd order polynomial.
Therefore it can have 2 real zeros or 2 complex zeros.
Because complex zeros always occur as conjugate pairs, there will be another complex zero which is a conjugate of the known complex zero.
For example, if the known complex zero is of the form (a + ib), then the other complex zero is (a - ib), or vice versa.
