Step-by-step explanation:

first do (x + 6)(x+6)

= (x^2 + 6x + 6x + 36)

multiply all by 2

2x^2 + 12x + 12x + 72

simplify and subtract 50

2x^2 + 24x + 72 - 50

2x^2 + 24x + 22

(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
