If 1 + 13i is a root of f(x), then 1 – 13i is also a root of f(x).

Answer:

' 1+13 i ' is a solution or root of f(x) then it's complex conjugate ' 1-13 i ' will also be a solution.

Step-by-step explanation:

" we know that a complex root always appear in pair so for any polynomial function f(x) if 'a+i b' is a solution or root then its complex conjugate 'a-i b' is also a solution for this polynomial function f(x) ".

Here we are given that ' 1+13 i ' is a solution or root of f(x) then it's complex conjugate ' 1-13 i ' will also be a solution.
