The solution of a/0 is undefined (it has real no meaning): http://en.wikipedia.org/wiki/Division_by_zeroyou have divided both sides by x-y=0.division by zero is "illegal".why?
consider p/0 = q; p and q are non-zero.
we have p=0*q.say p=10
no value of q when multiplied with 0 will give you 10.
please comment,if you feel that there are faults with my posts or if i can improve my explanations...thank you
