Do you need to factorize it or expand it?

factorize
Use \(a^3 - b^3 = (a-b)(a^2+ab+b^2)\)
FYI, 64=4^3
I believe the answer is: \[6x^3+384\]
i started off with 6x^3 +384
distribution :) sir abbot is right
Factorize.. not expand..
And if you started from 6x^3 +384, you shouldn't get 6(x^3-64)...
i got 6(x^3-64)
What is the original question?
factor 6x^3-384
= 6x^3-384 or 6(x-4)(x^2+4x+16)
@mike12 Then you did right. 6x^3-384 = 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 \(a^3-b^3 = (a-b)(a^2+ab+b^2)\) to factorize x^3 - 4^3. Can you do it?
ill try
give me a second
Take your time :)
lol yeah im pretty lost
Where?
applying the identity
Have you learnt that identity yet?
yeah but actually trying to sub it in...having troubles
What troubles? Can you show your work?
honestly just plugging in the equation... i dont know what to plug in or where
Compare \(x^3 - 4^3 \) and \(a^3-b^3\) Can you identify what is a and b?
yeah
What are they then?
@mike12 What are a and b...???
