Question

What is the value of
$(x + y) ^3$
​

Answer 1

By using the identity:

$\tt \boxed {\underline{ \red{(a + b) {}^{3} = a {}^{3} + 3a {}^{2} b + 3ab {}^{} + b {}^{3} }}}$

$\sf(x + y) {}^{3} = {x}^{3} + 3 {x}^{2} y + 3(x)(y) + y {}^{3}$

More information:

(a + b)2 = a2 + 2ab + b2

(a - b)2 = a2 - 2ab + b2

(a + b)(a - b) = a2 - b2

(x + a)(x + b) = x2 + x(a + b) + ab

(a + b)2 = a2 + 2ab + b2

(a - b)2 = a2 - 2ab + b2

(a + b)(a - b) = a2 - b2

(a + b)3 = a3 +3a2b + 3ab2 + b3

(a - b)3 = a3 - 3a2b + 3ab2 - b3

(a + b + c)2 = a2 + b2 + c2 + 2ab + 2bc + 2ac
