Well 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???

What 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.

like 4+ root 12 is the same as: \[\pm 2 \sqrt{3}4\] (sorry I constrantly right wrong)

The answers is the same abbie no need to worry. \[2(\sqrt{3}2)=2\sqrt{3}4\] Just 2 multiplied into the parentheses.
