${\tt{\blue{a^2 + 2ab + b^2}}}$

Gain Extra information!!!!!!

${\tt{\blue{1)(a-b)^2}}}$

$\leadsto{\tt{\pink{a^2 - 2ab + b^2}}}$

${\tt{\blue{ 2) \: a^2+b^2}}}$

$\leadsto{\tt{\pink{(a+b)^2+ 2ab}}}$

$\leadsto{\tt{\blue{(a+b)^2 -2ab}}}$

${\tt{\blue{3)\: a^2 - b^2}}}$

$\leadsto{\tt{\green{(a+b)(a-b)}}}$

${\tt{\blue{4)\: (a+b)^3}}}$

${\leadsto\tt{\orange{a^3+ b^3+3a^2b + 3ab^2}}}$

${\leadsto\tt{\red{a^3+ b^3+3ab(a+b)}}}$

${\tt{\blue{5)\:(a-b)^3}}}$

${\leadsto\tt{\red{a^3 - b^3-3a^2b + 3ab^2}}}$

${\leadsto\tt{\orange{a^3- b^3-3ab(a-b)}}}$
