(a+b)^(2) = a^(2) + 2ab + b^(2)
(a-b)^(2) = a^(2) - 2ab + b^(2)
(a+b)(a-b) = a^(2) - b^(2)
(a+b)^(3) = a^(3) + b^(3) + 3ab(a+b)
(a-b)^(3) = a^(3) - b^(3) - 3ab (a-b)
a^(3)+b^(3) = (a+b)(a^(2) - ab + b^(2))
a^(3) - b^(3) = (a-b)(a^(2) + ab + b^(3)
a^(3) + b^(3) + c^(3) - 3ab =(a+b+c)[ a^(2) + b^(2) + c^(2) - ab -bc-ca]
2 3 2
:-)
(a+b+c)[a^(2) + b^(2) + c^(2) - ab - bc - ca]
this is also there
thanks
u r welcome!
