when simplifying roots, thing about the factors of the number you are simplifying. 12 has factors of 4 and 3. Under the square root I can show 4 x 3 instead of 12. Then I can just take the square root of 4, which is 2, and leave the 3 inside the square root, because it can no longer be simplified. This leaves me with 2 * the square root of 3
