In Exercises 64-68, use a graphing utility to determine whether the divisions have been performed correctly. Graph each side of the given equation in the same viewing rectangle. The graphs should coincide. If they do not, correct the expression on the right side by using polynomial division. Then use your graphing utility to show that the division has been performed correctly. 68. x 3 + 3 x 2 + 5 x + 3 x + 1 = x 2 − 2 x + 3
