Two days ago "Steve" helped me with this problem. I am grateful to him. I didn't get it and asked for him to help me again. He showed it to me again, but I needed more steps shown. Then I think he was finished for tutoring for the day before I could see it again with more steps. I understand factoring out the 1/3 on the left hand side and I understand factoring the denominator on the right hand side. After that I have problems. Please help me. The problem is: (x/(3x+6))- ((x+1)/(3x-6))=1/((x^2)-4)
