Question

The two roots a+(radical)b and a-(radaical)b are called __________ radicals

Answer 1

They are called conjugate roots

Answer 2

Irrational conjugates.

Explanation:

The given roots are

`(a+√(b))   (a-√(b))`

The two expressions are conjugate.

Here
`√(b)` is an irrational number.

The irrational conjugates theorem states that if a + √b is an irrational root to a polynomial, then its irrational conjugate a - √b is also a root.
