|\begin{matrix} 1 & a^{2} + b c & a^{3} \\ 1 & b^{2} + c a & b^{3} \\ 1 & c^{2} + a b & c^{3} \end{matrix}| = - (a - b) (b - c) (c - a) (a^{2} + b^{2} + c^{2})

A - (B \cup C) = (A - B) \cup (A - c)

A - B = A - (A \cap B)

A = (A \cap B) \cup (A - B)

|\begin{matrix} a^{3} & 2 & a \\ b^{3} & 2 & b \\ c^{3} & 2 & c \end{matrix}| = 2 (a - b) (b - c) (c - a) (a + b + c) \begin{matrix}  \end{matrix}
