I am trying to teach myself mathematical induction, have never encountered this before and it's giving me trouble. My problem will likely be very easy to you all so please forgive me.

I have put up the scanned image of the example in my book.

here are my 3 questions:

(1)What I don't understand is that how do I get the values in #2 (red ink) from #1. It seems like it's some basic factoring operation but I'm very confused even looking at this example. I have tried to get the values in #2 from #1 but they don't match up. It seems like the text decided to jump a step or maybe I just don't understand it's simple steps.

(2)How do we know when we've completely solved an inducation problem? for eg: in addition we know we've arrived at the answer when we can't add anymore. :D How do we know when we've solved the problem in induction?

(3)I would appreciate it if you can give me some basic tips regarding and how to do induction problems. This book I have doesn't go into it much besides showing examples. I think I understand most of it after having looked at three examples and stressing myself out the past 2 days trying to learn. The book just gives me the basic principles for inducation (1)Prove that it is true for n=1 (2)Assume it is true for n=k (3) use this to prove that n=k+1 is true. I would also be greatful if you can recommend me any good books regarding basic Algegra & Geometry.

Please help me as I'm taking this self learning course and don't have anyone to ask for help. I have an entrance exam in less than three weeks. Appreciate all kind help :D
