Best ResponseYou've already chosen the best response.0use the formula : a^3 + b^3 = (a+b)(a^2  ab + b^2) 27x^3 + 512y^3 = (3x)^3 + (8y)^3 now, use the formula above to get of factors a^3 + b^3 = (a+b)(a^2  ab + b^2) we have (3x)^3 + (8y)^3 it means a = 3x and b = 8y therefore, (3x)^3 + (8y)^3 = (3x+8y)((3x)^2  3x(8y) + (8y)^2) (3x)^3 + (8y)^3 = (3x+8y)(9x^2  24xy + 64y^2) so, it is C I found your problem already answered hopefully this helps.
