What are the coordinates of the points where the graphs of f(x) = x^3 - x^2 + x + 1 and g(x) = x^3 + x^2 + x + 1 intersect? Give your answer as a list of points separated by semicolons, with the points ordered such that their x-coordinates are in increasing order. (So "(1,-3); (2,3); (5,-7)" - without the quotes - is a valid answer format.)
