Question

(a+b)(a+b)(a+b) what is the formula​

Answer 1

$(a + b)(a + b)(a + b) \: = {(a + b)}^{3}$

$\implies \: (a+ {b)}^{3} = \underline{ \underline{ \bold{ {a}^{3} +3 {a}^{2} b+3 {ab}^{2} + {b}^{3} }}}$

Answer 2

Step-by-step explanation:

a²+b²+2ab=(a+b)²

a²+b²-2ab=(a-b)²

a²-b²=(a+b)(a-b)

a³+b³=(a+b)(a²+b²-ab)

a³-b³=(a-b)(a²+b²+ab)

a³+b³+c³-3abc=(a+b+c)(a²+b²+c²-ab-bc-ca)

a³+b³+3ab(a+b)=(a+b)³

a³-b³-3ab(a-b)=(a-b)³
