Hi,
"In mathematics, the complex conjugate root theorem states that if P is a polynomial in one variable with real coefficients, and a + bi is a root of P with a and b real numbers, then its complex conjugate a − bi is also a root of P."
Based on above theorem, how come below answer is not (B) a-bi.
Am I missing something?
