On a graph, the equation #r = 2 sin theta - 1# has occupies exactly the same points as the graph #r = 2 sin theta + 1#

However, if you simplify it,
#-r = x^2 + y^2 - 2y#
#-r = r^2 - 2r sin theta#
#-1 = r - 2 sin theta#
#r = 2 sin theta -1#

When the equation #r = x^2 + y^2 - 2y# is squared, we introduced the equation #-r = x^2 + y^2 - 2y# too.
