(a-b-c)( a² + b² + c² +ab+bc+ca)
(a-b-c){(-a)² +(-b)² +(-c)² -(a×-b)-(-b×-c)-(-c×a)}
a^3 +(-b)^3 +(-c)^3 -3(a-×b×-c) [∵(x+y+z)(x^2+y^2+z^2-xy-yz-zx)]
a^3-b^3-c^3- 3abc
(a-b-c){(-a)² +(-b)² +(-c)² -(a×-b)-(-b×-c)-(-c×a)}
a^3 +(-b)^3 +(-c)^3 -3(a-×b×-c) [∵(x+y+z)(x^2+y^2+z^2-xy-yz-zx)]
a^3-b^3-c^3- 3abc
