Best ResponseYou've already chosen the best response.0Then I used the quadratic formula to get \[\frac{ 1\pm \sqrt{217} }{ 2}\]

Best ResponseYou've already chosen the best response.0I think that the problem is with the number in the square root.

Best ResponseYou've already chosen the best response.0Yes, I think I may have figured out the problem. For some reason my calculator was spitting out sqrt(217) but I think it should be Sqrt(225)

Best ResponseYou've already chosen the best response.0I can't figure out for the life of me where my calculator came up with 217 instead of 225

Best ResponseYou've already chosen the best response.1There is a few different ways you can solve \(\rm \color{purple}{x^2+x52=4}\) One way is without square roots I was going to show you :)

Best ResponseYou've already chosen the best response.1Hmm, are you using like a calculator on your computer or..?

Best ResponseYou've already chosen the best response.0Yes, so I used a different one which is where I got the correct answer.

Best ResponseYou've already chosen the best response.1Ah ok. You must've used 217 in the past, and it was suggesting this and that. Weird to explain. Clearing your history should work or just use a different calculator for now on :)
