The answer is__________
Multiple of
= ( a + b - 2 ) [ ( a + b ) ^ 2 + 2 ( a + b ) + 4 ]
= ( a + b - 2 ) [ ( a ^2 + 2ab + b ^2 + ( 2a + 2b ) + 4 ]
= ( a + b - 2 ) [ ( a^2 + b^2 + 2ab + 2a + 2b + 4 ) ]
= ( a + b - 2 ) [ ( a^2 + b^2 + 2 ( ab + a + b ) + 4 ) ]
= { [ a^3 + ab^2 + 2a ( ab + a + b ) + 4a ] + [ a^2b + b^3 + 2b ( ab + a + b ) + 4b ] - 2 [ a^2 + b^2 + 4 ( ab + a + b) ] }
