Best ResponseYou've already chosen the best response.0For (a+4)^3 (a+4)^3=(a+4)(a+4)(a+4) 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, (a+4)(a+4)(a+4) When you distribute, you will get (a^2+8a+16)(a+4) Then try expanding it again.

Best ResponseYou've already chosen the best response.0(a^2+8a+16)(a+4) 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
