4. Which statement about the zeros of a quadratic polynomial is true?
There must be one complex zero, not just real zeros.
O If - 4 and 3 are zeros, the conjugates 4 and - 3 must also be zeros.
If the quadratic polynomial has three zeros, then it must have complex coefficients.
If the polynomial is quadratic, then it can have a maximum of two zeros, not three.
