x%28sqrt%2818%29%29-3sqrt%288x%5E2%29
Rewrite the terms under the radical in terms of their factors to see what can be pulled out:
x%28sqrt%282%2A3%2A3%29%29-3sqrt%282%2A2%2A2%2Ax%2Ax%29
You should now recognize that you can pull out a 3 from the first term and a 2x from the second, giving you:
3x%28sqrt%282%29%29-6x%28sqrt%282%29%29
You can now combine the 2 terms, since they are each represented by sqrt%282%29:
highlight%28-3x%28sqrt%282%29%29%29
Good Luck,
