I want to solve x%5E2%2B3x-4=0 by "completing the square", I have a textbook and some animations but I just do not get it. I had a problem with quadratic formula and I found an example on this website that just made that click for me. I am hoping someone can do the same with "complete the square". Thanks in advance for you explanation.
