Question

How is adding radical expressions similar to adding polynomial expressions? How is it different? Provide a radical expression as an example.

Answer 1

You can only add or subtract two polynomial terms together if they have the same variables; terms with matching variables are called "like terms." Radicals work in a very similar way.

Sample radical expression:

3(sqrt{2xy}) - 2(sqrt{50xy})
