Any unit circle that is tangent to both principal arises must have centres \( (1,1),~(1,-1),~(-1,-1),\text{ or }(1,-1)\)

The problem is not well stated. Given only that the circle is tangent to the axes and has radius 1, we can't conclude that it must be any one of those circles. It should say something like, "... then its equation may be:" or "Which of the following equations represents a circle that ...".

Find the center of each circle, and see if it fits the requirements.

Okay, that's understandable, thankyou man.
