Question

According to the complex conjugated theory if -3+i is a riot of a function what else is a root?

Answer 1

[tex]-3-i[/tex]

Explanation:

Complex conjugate root theorem states that if a+bi is a root for a function then its complex conjugate a-bi is also a root of the function.

Now given that -3+i is the root of a function .

The complex conjugate of the above complex number is -3-i.

(∵ Complex conjugate can be obtained by simply substituting i with -i in the given complex number )

By complex conjugate root theorem its complex conjugate -3-i is also a rot of the function.
