Use \(a^3  b^3 = (ab)(a^2+ab+b^2)\)

I believe the answer is: \[6x^3+384\]

Factorize.. not expand..

And if you started from 6x^3 +384, you shouldn't get 6(x^364)...

= 6x^3384 or 6(x4)(x^2+4x+16)

@mike12 Then you did right. 6x^3384 = 6(x^3  64) Note that 64 can be written as 4^3, so you get = 6(x^3  4^3) Next apply the identity \(a^3b^3 = (ab)(a^2+ab+b^2)\) to factorize x^3  4^3. Can you do it?
