10-3 OPERATIONS WITH RADICALS Objectives: to simplify products and quotients of radical expressions.

Let’s practice distributing Answer: -2√ √2

Conjugates Conjugates – the sum and difference of the same two terms. Examples: You can use conjugates to simplify a quotient whose denominator is a sum or difference of radicals. Can you list more examples of conjugates?
