a*a(b - c) + b*b(c - a) + c*c(a - b)
= a”b - a”c + b”c - b"a + c"( a - b )
= a"b - ab" - a"c + b"c + c"( a - b )
= ab( a - b ) - c( a" - b" ) + c”( a - b )
= ab( a - b ) - c( a + b )( a - b ) + c"( a - b )
= ( a - b )( ab - ac - bc + c" )
= a”b - a”c + b”c - b"a + c"( a - b )
= a"b - ab" - a"c + b"c + c"( a - b )
= ab( a - b ) - c( a" - b" ) + c”( a - b )
= ab( a - b ) - c( a + b )( a - b ) + c"( a - b )
= ( a - b )( ab - ac - bc + c" )
