Sagot :
Answer:
Given that is a zero of a quadratic function with real coefficients, we know that complex conjugate pairs are also zeros for a quadratic function with real coefficients. Therefore, the complex conjugate of 4-5i is also a zero.
To find the complex conjugate of 4-5i , we simply change the sign of the imaginary part. So, the complex conjugate of is 4-5i.
Therefore, if is a zero of the quadratic function, then will also be a zero.
