Question
If D =
for x ≠ 0, y ≠ 0 then D is
for x ≠ 0, y ≠ 0 then D isOptions
A.divisible by neither x nor y
B.divisible by both x and y
C.divisible by x but not y
D.divisible by y but not x
Solution
D = 
C2 → C2 - C1 & C3 → C3 - C1
= xy.
Hence D is divisible by both x and y.

C2 → C2 - C1 & C3 → C3 - C1
= xy.Hence D is divisible by both x and y.
