Gorgias, pollus, callicles

I need help with a Law question. All explanations and answers will be used to help me learn.

In Plato’s Gorgias, Socrates engages 3 different rhetoricians on the nature of rhetoric: Gorgias, Polus, and Callicles. What are the basic claims about the nature of rhetoric by each of these characters, and how does Socrates respond to their claims? Why is Socrates so interesting in understanding the nature of rhetoric? Does Socrates get the answer that he desires?

quote and cite the text of the dialogue to support your position.

PLEASE DO NOT ACCEPT THIS QUESTION IF YOU HAVE NOT READ PLATO GORGIAS.
