Dear himank


If the function is define at that point in which point u are finding the limit then u can find it directlt as an example given by u


x=3 is in the domain of function 3x^2-4x-10  so u can find by direct .


but if the function is not define at the point where u are finding the limit then u can't use the direct method


such as   f(x) = (x2-x )/x   tis function is not define at x=0


 so u can't find limit by just direct putting.


      in this case u have to take common x and then u can put the value x=0
