Question 2
according to the complex conjugates theorem, if 5 - ¿ is a root of a function what else is a root?
o 5ti
5ti
5i
-5 - i

Step-by-step 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:
