Answer:

Explanation:
By definition, you know that the Complex numbers have the following form:

Where "a" and "b" are real numbers and "i" is the imaginary unit (Remember that
)
Having a polynomial P(x) with real coefficients, the Complex Conjugates rTheorem states that if
is a root of the the polynomial, then its complex conjugate
is also a root of the polynomial.
In other words, this Theorem states that the complex roots always appear in conjugate pairs.
Based on this, if you have the following root of a function:

Then, its complex conjugate is also root of a function. This is:
