Ответ:

Объяснение:

1) Разность кубов
$27-x^{3}=3^{3} -x^{3}=(3-x)(9+3x+x^{2} )$

2)сумма кубов

$8a^{9}+b^{6}=2^{3}(x^{3} )^{3} +(b^{2} )^{3} =(2x^{3} )^{3} +(b^{2} )^{3}=$

$=(2x^{3} +b^{2} )(4x^{6}-2x^{3}b^{2} +b^{4})$

3) Сумма кубов (свернуть по формуле):

$(2a+3b)(4a^{2} -6ab+9b^{2} )=8a^{3}+27b^{3}$
