Conjugates in Algebra

The question:

How do we identify the conjugate of an expression


The answer:

I’m going to give you a couple of example types that come up in algebra all the time:

Given: 1 + √3

The conjugate is: 1 - √3


Given: x + bi

The conjugate is: x - bi



In algebra, conjugates are usually associated with the difference of squares formula.


The difference of squares formula states that:

(a + b)(a - b) = a² - b²


This idea can be applied to factoring or rationalizing the denominator.



Thanks for writing.

Definition of Conjugates NEW
by: Nadia

I have not seen a definition of a conjugate on any website. I see only examples to explain them. Does anyone have a written definition, not more examples?
