Substitute x, y, z for λ in ( ∗ 1) and sum, we get x 3 y 3 z 3 − a ( x 2 y 2 z 2) b ( x y z) − 3 c = 0 This is equivalent to x 3 y 3 z 3 − 3 x y z = x 3 y 3 z 3 − 3 c = a ( x 2 y 2 z 2) − b ( x y z) = ( x y z) ( x 2 y 2 z 2 − x y − y z − z xSolve your math problems using our free math solver with stepbystep solutions Our math solver supports basic math, prealgebra, algebra, trigonometry, calculus and more25 6 oluyor 25, Mart, 15 sonelektrikbukucu ( 29k puan)

So substituting the values for the elementary symmetric polynomials that we found, we find that x, y and z are the three roots of t3 −t2 − 1 2t − 1 6 = 0 or if you prefer 6t3 − 6t2 −3t −1 = 0 In theory we could solve this using Cardano's method and directly evaluate x4 y4 z4, but the methods used above are somewhat easier1 solution(s) found x^33xy^33yz^33z x^33xy^33yz^33z See steps Step by Step Solution Reformatting the input Changes made to your input should not affect the solution (1) z3 was replaced by z^3 2 more similar replacement(s)Complete cubic parametrization of the Fermat cubic surface w 3 x 3 y 3 z 3 = 0 This is a famous Diophantine problem, to which Dickson's History of the Theory of Numbers, Vol II devotes many pages It is usually phrased as w 3 x 3 y 3 =z 3 or w 3 x 3 =y 3 z 3, with the implication that the variables are to be positive, as in the integer solutions 3 3 4 3 5 3 =6 3 (an amusing
