Hello,
Im completely new here and i am very sorry if similar topic exist, though search did not bring up any reasonable answers.
I seem to be unable to solve an inequation involving absolute value. That is to say that i get different answer from that provided in the book. I uploaded a picture with my problem + solution. I hope it makes sense there. Im sorry if it is messy, im just getting used to the graphic pad. The problem is, that the book says answer should be from -infinity to -1, but i get from -infinity to -1/4. Many thanks in advance
