Q:

If a polynomial function f(x) has roots 3 and mc001-1.jpg, what must also be a root of f(x)?

Accepted Solution

A:
i cannot see what mc001-1.jpg is, but i assume it is a complex number. so according to the irrational root theorem, if a + √b is a root of a polynomial equation where a and b are rational numbers and √b is an irrational number, then a - √b is also a root

the answer would be the complex number given with the opposite sign before √b.

if this doesn't help and you need more clarification, comment what mc001-1.jpg is and i'll be happy to help.
