Since the limit becomes the undetermined form

it means that both polynomials have a root at
. So, we can fact both numerator and denominator:


So, the fraction becomes

Now, as x approaches 1, you have no problems anymore:

In this question, it is given that y varies inversely as x . So the equation is

And here k is the proportionality constant .
And when x=6, y=12

So the values of the proportionality constant k is 72 and the correct option is B.
Answer:
it will be x = 2 sorry if I am wrong
