Factor completely 4x^2-32

4(x+4)(x-4)
4(x+4)(x-8)
4(x^2-8)
Prime

4(x²-8) is correct

Step-by-step explanation:

If you solve this you get 4x²-32

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

i dont know sorry
