What value of X will make the following equation true?
14x - 12 = 4 - 42x

The answer to the equation is  

First, you must add 12 on each side

Then, you add 42x on each side

Finally, divide each side by 56

(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
