ok the answer that i have that is really not completed is correct or not?
ok i will try i am kinda rusty on this i havent did this for a long time
So, you can apply FOIL to (a+4)(a+4)(a+4) , two times.
It is not complete, you have to apply the FOIL method,
When you distribute, you will get
Then try expanding it again.

There are some examples learning FOIL here: http://www.mathsisfun.com/algebra/polynomials-multiplying.html
no.. it is 48a
48a where i have my ? at
i am trying to figure out how o get that number thats all and i keep getting answers that is not helping on how to find...
so could you please show me how did you get 48a?
Or If u knw Binomial Theorem Use it..)
ok lets see here i am going to figure out how you got 48a
When you're here, there's a shortcut to look at the coefficient of a, you look at which multiples gives you 'a'.
From here you can see that 8a multiply by 4 gives you 32a
And 16 multiply by a gives you 16a
Since its adding up, 32a+16a=48a
thank you so it is a^3+12a^2+48a+64
ok i dont remember using that it has been years so some of this stough i remember how to....
i feel old brained
now i get it i am so sorry ppl thank you so much for bearing with me i havent been in school fo a long time and i am warming up on old math memories
