Best ResponseYou've already chosen the best response.0Well is you answer right? x=2(3√−2) x=−2(3√+2) I completed the square and got 4+ root 12?? How would you simplify that???

Best ResponseYou've already chosen the best response.1What I wrote is the quadratic formula you had hardships rewriting... mearly a rewriteing, nothing else... This "Completing the square"method I'm not familiar with... unless we have another name for it in my native language.
