Here x & y can be any value. x can be +/- & y can be +/- or both can be zero
Qt A
xy+7
Qt B
xy + 7x
If we take x = y = 0 then Qt A > Qt B
But
If we take x = 1 & y = 1 then Qt A = Qt B
Answer D
Qt A
xy+7
Qt B

If we take x = y = 0 then Qt A > Qt B
But
If we take x = 1 & y = 1 then Qt A = Qt B

Hi,
Qty A- xy+7
Qty B- x(y+7)= xy+7x
Subtracting xy on both the sides.
Qty A- 7
Qty B-7x
Now there can be different answers depending on the value of x i.e. x-0 or 1 or -1 etc.
Thus D is the answer.
Hope this helps!!
