another book about fundmental theorem of algebra problem...

another problem in another book( p.251-252, A first course in complex analysis with applications By Dennis G. Zill, Patrick Shanahan):

A first course in complex analysis ... - Google Books

How does the author conclude the theorem is true after he state the inequality at the bottom of the page of p.251-p.252

(after that inequality,i don't know anything)?

Since those pages are not shown in the preview, I doubt anyone can answer the question. Although, I strongly suspect that it will be - again - a case of where you currently do not have the necessary prerequisite knowledge to follow the proof. I suggested in another thread that you use a certain type of book. My suggestion remains.

But i could see the preview,i think the people in new york can also see it,also,i think i just have problem with the conclusion in that section...

Pages 157-252 are NOT shown (for me, anyway). This does not change what's said in post #2.

Look at my reply in this thread.

Everything I said there applies to Zill.
