1.
(a + b)(a + b)
a^2 + ab + ab + b^2
a^2 +2ab + b^2
2.
3.
a^2 - ab + ab - b^2
a^2 - b^2
4.
(a + b)(a + b) × (a + b)
(a^2 + ab + ab + b^2)(a + b)
(a^2 + 2ab + b^2)(a + b)
a^3 + a^2b + 2a^2b + 2ab^2 + ab^2 + b^3
a^3 + 3a^2b + 3ab^2 + b^3
5.
(a - b)(a - b)(a - b)
(a^2 - ab - ab + b^2)(a - b)
(a^2 - 2ab + b^2)(a - b)
a^3 - a^2b - 2a^2b + 2ab^2 + ab^2 - b^3
a^3 - 3a^2b + 3ab^2 - b^3
6
(a + b + c)(a + b + c)
a^2 + ab + ac + ab + b^2 + bc + ac + bc + c^2
a^2 + 2ab + 2ac + b^2 +2bc + c^2
