((x + y)/x)+((x - y)/y)-((x2 - y2)/xy) =?
Solution
Correct Answer: Option D
((x + y)/x)+((x - y)/y)-((x2 - y2)/xy)
= ((xy + y2 + x2 - xy)/xy) - ((x2 - y2)/xy)
= ((x2 + y2)/xy) - ((x2 - y2)/xy)
= (x2 + y2 - x2 + y2)/xy
= 2y2/xy
= 2y/x
= ((xy + y2 + x2 - xy)/xy) - ((x2 - y2)/xy)
= ((x2 + y2)/xy) - ((x2 - y2)/xy)
= (x2 + y2 - x2 + y2)/xy
= 2y2/xy
= 2y/x
