is that your answer
that is your answer.
\[x=2(\sqrt{3}-2)\] \[x=-2(\sqrt{3}+2)\]
Wait but can't you also do it by completing the square??
im so confused. are you suposed to get the same answer no w=matter what method you use???
Yes you are :)
Unless we use aproximation methods.
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.
thanks!
like -4+- root 12 is the same as: \[\pm 2 \sqrt{3}-4\] (sorry I constrantly right wrong)
Yes..but couldn't the -4 go in front?? thats not the same as your answer.. which is right??!??!?!!!!
The answers is the same abbie no need to worry. \[2(\sqrt{3}-2)=2\sqrt{3}-4\] Just 2 multiplied into the parentheses.
thanks!!
