AFinal answer:
The regex '\(..\)' matches two characters enclosed in parentheses in a text, taking the parentheses literally and using periods to signify any character.
Step-by-step explanation:
The regex '\(..\)' is used to match a specific pattern within a text. This regular expression will search for two characters enclosed in parentheses.
The backslashes before the parentheses indicate that the parentheses are to be taken as literal characters rather than as special characters used for grouping in regex patterns.
The two periods inside the parentheses '.' represent any character (except a newline), and because there are two periods, the regex will match any two characters.
For example, in the string 'The (xy) are coordinates', this regex would match '(xy)' because it's a group of two characters inside of literal parentheses.
