Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Refer attached option d is correct
if x= lamda, you can't cancel then what?
why we cant cancel.? If x =lembda , then we can solve in this way .
doubt
please answer
since f(x) is polynomial function and hence continuous on R . So f(lembda) = lim(x tends to lembda) f(x)
inverse of (x-lembda) is 1/(x-lembda) . So (x-lembda)/(x-lembda)= 1 . We can easily cancel as field is R .
