Please refer to the attachments for the question (focus part inside red outline) and my working out:
How come I am only getting one of the solutions (x = 1)?? I know that x = 0 and x= - 1 turn out to be invalid solutions (using previous calculations not shown in this post) and you end up using x = 1 anyway but I'm not sure what I am doing wrong in that I am not getting ALL solutions?
