Question

Fill in the blank to complete the following sentence. If a polynomial has one root in the form a+ V6, it has a second root in the form of a _v5.

Answer 1

The correct answer is: plus (+)

Explanation:

"+"

Answer 2

Given:

Is a polynomial has one root in the form of

`a+\sqrt[]{b}`

Then it has a second root in the form of _____.

We know that the complex roots occur in conjugate pairs so we have another root in the form of:

`a-\sqrt[]{b}`

Hence, the answer is:

`a-\sqrt[]{b}`
