I need to find the real solutions to a simple equation:

It seems that there should be two real solutions to the equation. However, I am told that the equation has only 1 real solution. (Headbang)

There is only one real solution: 2.79129.

In your first step, you squared both sides. You forgot that it is "plus or minus" though, when you do that. Make sense?
