The inequality is equivalent to:
Taking squares and smplifying:
This is absurd because
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 ?
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 .
