Hello I’m an 8th grader having difficulties with Pythagorean theorem, it’s not math I can post on here. Can someone drop any socials to help me - Discord, snap, insta, # - anything is okay

well my insta ins marysheets511 i can help you

Step-by-step explanation:

(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
