So, after rearrangement, [(x - 2).sup.3] = -4/3 and this problem reduces to finding the cube roots of -4/3, which by de Moivre's method are found to be -1.101, 0.55 - 0.953i, and 0.55 + 0.953i Now add 2 to these results to find the three roots of the original equation, viz., 0.899, 2.55 - 0.953i and 2.55 + 0.9537 It is observed that a general cubic will have three roots which when plotted in the Argand plane will form an isosceles triangle.
