Question

show that n2-n is divisible by 8, if n is odd positive integer.

Answer 1

n^2-n=n(n-1)
Put n=3 so here 3×2
n=5 so 5×4
n=7 so 7x6
n=9 so 9×8 add n= 17,25,33 add 8 in each no further all aee divisible by 8

Answer 2

Answer:

Here it iss...

Step-by-step explanation:

n^2-n=n(n-1)

Put n=3 so here 3×2

n=5 so 5×4

n=7 so 7x6

n=9 so 9×8 add n= 17,25,33 add 8 in each no further all aee divisible by 8
