I'm afraid that if a poster can't be bothered to spell equality correctly and post a meaningful question then it's unlikely anyone is going to go to the trouble write a 200o word essay for them. I know this is course work because pretty much the same question is asked fairly regularly on here. If you google the question you'll find loads of answers, but maybe you'd benefit from trying to answer it yourself based on your course notes and text books.
There are loads of things you can put in an essay like this.
