If the square of polynomial x + 2 times the square of (k-1) XY + y, K does not contain the term of XY, the value of K is obtained If the square of polynomial x + 2 times the square of (k-1) XY + Y - K does not contain the term of XY, the value of K is obtained

If the square of polynomial x + 2 times the square of (k-1) XY + y, K does not contain the term of XY, the value of K is obtained If the square of polynomial x + 2 times the square of (k-1) XY + Y - K does not contain the term of XY, the value of K is obtained

2 (k-1) = 0
The solution is k = 1
