Write the equation of the line that passes through (-5, 3) and has a slope of -4. y – 3 = -4 (x – 5)
y + 3 = -4 (x + 5)
y + 3 = -4 (x – 5)
y - 3 = -4 (x + 5)

(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
