Question

a polynomial function has -5
`√(3t)` as a root. which of the following must also be a root of the function?

Answer 1

-5-√3i

Explanation:

Answer 2

`5 √(3)i`

Explanation:

Assuming one root of a polynomial function is

`- 5 √(3) i`

Then the other root is

`5 √(3)i`

The reason is that , complex roots of polynomial functions occur in pairs.

One complex root is the conjugate of the other.

This means that, if

`x - yi`

is a root, then

`x + yi`

is also a root.
