Answer 8

(2n-1)^2 = 4n^2 - 4n + 1

= 4(n^2 - n) + 1

If n is even, n^2 and n are both even, so n^2 - n is even
If n is odd, n^2 and n are both odd, so n^2 - n is even

So, whatever the value of n, n^2-n is even, so can be written as 2k (where k is an integer)

Hence 4(2k) - 1 = 8k-1

Answer 9

@gorv
thank u

Answer 10

@gorv
plse see the solution again
when we put 2k= 4(n^2 - n)
in 4(n^2 - n) + 1, it is coming 8k+1 not 8k-1
