1. The problem statement, all variables and given/known data Simply enough, solve the following using U-Substitution. dy/dx = y2-2y+1 and the answer key provides y = 1+(x+C)-1 2. The attempt at a solution I know how to do this, I thought. But i'm just spinning my wheels and need somebody to show me my error... I tried moving around the dy/dx parts, so that I eventually ended up with dx=dy/(y2-2y+1) which simplified to x=ln(y2)2y-ln(2y)2+y, but thats not right, unless I'm missing some kind of simplification? Honestly, I have no idea where the textbook got the answer. Any tips? What am I doing wrong?
