Hey if you're using x and y, then what's with the x1 and x2? Sometimes people use x and y with these problems and sometimes they use x1 and x2. Repost the problem with either x and y or x1 and x2, not both. Also look at two exactly like it I solved yesterday. http://www.algebra.com/tutors/students/your-answer.mpl?question=1198985 http://www.algebra.com/tutors/students/your-answer.mpl?question=1198296 Edwin
