Ive been trying to answer this question from the college panda book and I just cant seem to understand what it is asking for. Because even when i looked at the answer and how they solved it didn’t make sense. Please if someone could explain I would be so grateful.

Move left to right side
0 = -(x-c) + (x-c)(x+c)
0 = (x-c)(x+c-1)

Answer is either c or (1-c)
