Conjugating a verb means writing out all of its forms and uses. There are more, but you get the idea. if you have formally studied a foreign language, you have probably encountered this, but it is rarely taught in English classes now.  You is used twice because it represents both the singular (one person) "you" and the plural (more than one person) "you". He, she, it, and "one" used as a pronoun all take the same verb forms.
