Combining like terms with negative coefficients and distribution
-2(2x+4)?

-4x - 8

Step-by-step explanation:

Step 1: Write out expression

-2(2x + 4)

Step 2: Distribute -2

-4x - 8

(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
