If u answer correctly then I will definitely mark u as brainliest

Answer 1

1.
$(b + c)( {a}^{2} - b - c)$

Answer 2

Solution 1.)

a^2 (b +c) - (b +c)^2

= (b +c) (a^2 - b - c)
________________

Solution 2.)

216a^3 - 1/27

= (6a)^3 - (1/3)^3

= ( 6a - 1/3) [ (6a)^2 + (1/3)^2 + (6a)(1/3)]

= (6a - 1/3)(36a^2 + 1/9 + 2a)
