Simplify:

Factor the numbers under the radicals (the radicands).

Notice that one of the factors under each radical is a perfect square.

So you can take the square root of these and move the result outside of the radical.
Now perfom the indicated multiplication.
Finally, combine like-terms.
...and there you have it!
