Hi guys,
for some reason this equation is giving me hard time. There shouldn't be a solution to it....and I do get one.
My mistake is somewhere in the first line, because Maple makes the same mistake if I let it start from my second line of solution.
My first line is to power each side, so I do ()^2 for each side, meaning that on the left side the square root is gone, and on the right side, I can something like (a-b)^2.
Somehow it doesn't work, can someone solve it please ?

I understand your question. First of all, when we write we are considering the positive root. It is not necessary to move the "2", but the solution is more complicated.
The original inequality is:
Tahing into account that , necessary:
If you solve , you will obtain:
If you take squares in without moving the "2" you will obtalin:
and this is a contradiction with .
