Here's the first problemWrite the following absolute value expressions as piecewise expressions.1. l x^2 - 1 lI don't want just an answer I would like the steps on how to do this, because I have about 8 other similar problems to do. Also if anyone who answers this would be willing to help me some other stuff I'll probably be posting more info. I have summer hw for Calculus and I can't remember half the stuff I should and am having trouble finding good information on how to do them. Again, I don't particularly want answers I want the steps. Thanks!. Created by Rachel R. science-mathematics-en - mathematics-en

Well, (x^2 - 1) is the difference of perfect squares. How to factor the difference of perfect squares is something you simply need to remember...|(x-1)(x+1)|Now, the absolute value can thought of as two different equations...(x-1)(x+1)and-1(x-1)(x+1)What to do really depends on what question is asked.
