Q:

# How do you add and subtract radicals?

A:

Radicals can only be added or subtracted when they are the same or can be made the same through simplification. A radical can be simplified by factoring out the radical of a whole number and finding its square root.

For example, two times the radical of three can be added to five times the radical of three for a total of seven times the radical of three. Addition and subtraction are possible in this instance because both numbers contain the radical of three. Adding together a radical of three with a radical of 75 is not possible until the radical of 75 is simplified.
