Question

A cube+2a square b +2ab square +b cube

Answer 1

Answer:

$(a + b)(a {}^{2} + ab + b {}^{2} )$

Step-by-step explanation:

$a {}^{3} + 2a {}^{2} b + 2ab {}^{2} + b {}^{3}$

using formula

$a {}^{3} + b {}^{3} = (a + b)(a {}^{2} - ab + b {}^{2} )$

.

$(a + b )(a {}^{2} - ab + b {}^{2}) + 2ab \times (a + b )$

$(a + b)(a {}^{2} - ab + b {}^{2} + 2ab)$

$(a + b)(a {}^{2} + ab + b {}^{2} )$
