Answer 1

Answer:

$= (a - b) {}^{3} + (b - c) {}^{3} + (c - a) {}^{3} \\ \\ = {a}^{3} - {b}^{3} - 3a {}^{2} b + 3ab {}^{2} + {b}^{3} - \\ c {}^{3} - 3b {}^{2} c + 3bc {}^{2} + {c}^{3} - {a}^{3} - \\ 3c {}^{2} a + 3ca {}^{2} \\ \\ = - 3a {}^{2} b + 3ab {}^{2} - 3b {}^{2} c + 3bc {}^{2} - 3c {}^{2} a + 3ca {}^{2}$
