I have been reading the compleate works of Lewis Carrol. A lot of people don't realise he was also a well respected mathematician. I came accross the equation x^2+7x+53=11/3. The first time I entered it into this calculator, it came up with a solution with imaginary numbers. But now, the second time, it comes up with a compleatly diffrent answer. I do not know if this is the calculator's falt, or if the equation is so nonsensical that it doesn't have one answer. Could someone please tell me an approxomate answer? It would be greatly appriciated. I know there is no real number answer fo this, but if i could have the closest possible answer in imaginary numbers, I would greatly appriciate it. Thank you.
^I asked this two weeks ago, but still haven't gotten an answer. I am adding that I origionaly did the problem four times, to check my answer, each time getting the same value in imaginary numbers. Now it does not work.
