so (x^2-1)/(x-1) =4= x^2-5+5....pretty sure you cant do that. x+1(x-1)/(x+1)=(x-1)=4 which equals (x^2-5x+5)/(x+1)=0..maybe i did something wrong,doesnt matter cuz that book clearly doesnt follow math rules.

I guess I forgot to mention that they performed basic algebra by making the statement say x^2 -5x + 5 = 0 ... which would be (2-5) (x+1) = 0 but that doesn't take away from the fact that you can't divide by 0 on the original problem. .right? if not, then I'm missing something.
