When $a \ne 0$, there are two solutions to $(ax^2 + bx + c = 0)$ and they are $$ x = {-b \pm \sqrt{b^2-4ac} \over 2a} $$

Programming Ruby: the classic “pick-axe” book. it’s a tome — i haven’t read it cover-to-cover. i think it’s useful for the first few chapters & then coming back to it as a reference when i need to get more in-depth on a topic: https://pragprog.com/book/ruby4/programming-ruby-1-9-2-0 — i’m a bit surprised that it seems not to have been updated for Ruby 2.1, 2.2, 2.3, or 2.4 :)
Ruby Koans: I found this really useful for getting over the initial learning curve with Ruby. Fun and approachable. http://rubykoans.com/ — I think this is also a bit dated, though likely still great for fundamentals
Michael Hartl’s Ruby on Rails Tutorial helped me get over the initial learning curve with Rails.
Learn Ruby the Hard Way — I have not read this one. It’s the newest learning-Ruby book that I know of, and I generally have a positive opinion of Zed Shaw’s “* the Hard Way” series.

I would recommend #4 and maybe #2 to someone starting with Ruby. #3 if you want to make sense of Rails. #1 as a reference, tho
