Best ResponseYou've already chosen the best response.1complete the square \(y=5x^210x13\) might be easier to do it starting with this \(y=5[x^2+2x+\frac{13}{5}]\)

Best ResponseYou've already chosen the best response.1we still haven't finished the first one if the answer is not x = 1, what is it?!

Best ResponseYou've already chosen the best response.0The first one, @IrishBoy123 showed you all the steps + proof. You said it is not the right answer without any reason. I am with him and don't get why you go to other one without finish the first one. :)

Best ResponseYou've already chosen the best response.1do it another way \(y=5x^210x13\) \(y' = 10 x  10\) \(y' = 0 \implies x = 1\)

Best ResponseYou've already chosen the best response.0because I entered that answer into the computer and it said it isn't right

Best ResponseYou've already chosen the best response.0I came to the same conclusion he had, I agree with him, but the computer doesn't.

Best ResponseYou've already chosen the best response.1You can check another way by finding the vertex, \[x= \frac{ b }{ 2a }\]

Best ResponseYou've already chosen the best response.0Guys they don't give you an option to do the problem a second time. I entered the answer and it was wrong so I just have to move on to the next question. Proving it to me over and over again will not change anything.

Best ResponseYou've already chosen the best response.0If you ever meet the developers of the program I'm working with you can argue with them about that. Thank you all for your help on that problem.

Best ResponseYou've already chosen the best response.1put each new question in a new thread and let's see if we can sort out that pesky computer of yours. perhaps you should wire it to a lie detector :p
