Step-by-step explanation:
Have/has got indicates possession of something, and the negative form (has not/hasn't got or have not /haven't got) shows a lack of possession.
For the subjects he, she, it, we use has got or the contracted form ('s). We write first the subject, then the has got and the rest of the sentence.
For the subjects we, you, they, I, and you, we use have got or the contracted form of it ('ve). First, we write the subject, then the have got and the rest of the sentence.
In the negative form, we write for he, she, it, the subject, then has followed by not or the contracted form hasn't and the got with the rest of the sentence. For we, you, they, I, and you, we write the subject, then have followed by not or haven't and got with the rest of the sentence.
When we want to ask a question, we write the has or have at the beginning of the question. Then the subject, the got, and the rest of the question.
