Evaluate a3+b3+c3−3abca^3+b^3+c^3-3abca3+b3+c3−3abc when a=1a=1a=1, b=2b=2b=2, c=3c=3c=3. What is the identity?
(a+b+c)(a2+b2+c2−ab−bc−ca)(a+b+c)(a^2+b^2+c^2-ab-bc-ca)(a+b+c)(a2+b2+c2−ab−bc−ca)
(a+b+c)3(a+b+c)^3(a+b+c)3
3(a+b)(b+c)(c+a)3(a+b)(b+c)(c+a)3(a+b)(b+c)(c+a)
(a+b+c)(a−b)(b−c)(c−a)(a+b+c)(a-b)(b-c)(c-a)(a+b+c)(a−b)(b−c)(c−a)
