Which of the following statement is not correct?

1. X + XY = X
2. X( X + Y ) = XY
3. X + XY = X
4. ZX + ZXY = ZX + ZY

Correct Option: A

Given X + XY = X
But X + XU = X + U
Hence option (A) is not correct.
X ( X + Y) = XX + XY = XY → correct
X + XY = X (1 + Y) = X → correct
ZX + ZXY = Z [X + Y] = ZX + ZY → correct
