hi!! so i dont understand this, i figured how to solve it the first time but i forgot, thank u!! :)

Answer 1

We need to remember that the sum of cubes have the next form

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

if a=6 and b=s therefore the polynomial expression that represents a sum of cubes is

$\mleft(6+s\mright)\mleft(s^2-6s+36\mright)$
