let's take a peek at the denominators
(x² - 4), (x + 2), (x - 2)
now x² - 4 is really x² - 2², which is a difference of squares, and therefore (x-2)(x+2).
from that, we can simply use the LCD of all denominators, which will then be just (x-2)(x+2), and multiply both sides by that LCD to do away with the denominators.
