Can anyone explain to me why this is incorrect?
1) multiple both sides of expression by 2
2) subtracting 2 from both sides
3) leaves you with 2squareroot6
Thanks

, I think you must have assumed that RHS of equation = 1. It doesn't say that. So the best we can do is to simplify the fraction.
Your math, I think:
\(\frac{2+2\sqrt{6}}{2}=\)
\(\frac{2+2\sqrt{6}}{2} = 1\) (NO) -
Multiply by 2 to clear the fraction
\(2+2\sqrt{6} = 2\)
Subtract 2 from both
\(2\sqrt{6} = 0\) (NO)
Look at your statement #1. . . "both sides of the equation." There is not a right hand side value. . . It's easy to do when you are in a hurry or tired.
You cannot assume that the right hand side equals one. Hope that helps.
