Complete the square.
If the right hand side is greater than zero, then it is the square of the radius of the circle centered at (3,-4).
.
.
If the right hand side is equal to zero, then it is a single point, namely the center (3,-4).
.
.
If the right hand side is less than zero, then the solution is the empty set.
