This might be a little to advanced for this forum, but I think it is a little bit to easy to post in linear algebra. My question is if there is a quick way to see the solution of this equation, solving y as a function of x, without using the 2nd degree equation formula. Here it is:
Thanks, I dont think I would have come up with that myself, but now it is clear. From the physical interpretation it is obvious that y = x is a (superfluos) solution, and although it is not trivial to perform the long division it is easier if you know what you are looking for.
