To evaluate the limit
, we can use algebraic manipulation and L'Hôpital's Rule.First, let's rewrite the expression:
We notice that direct substitution of
results in an indeterminate form
. To resolve this, we can multiply the numerator and the denominator by the conjugate of the numerator:
The numerator simplifies as follows:
So the expression becomes:
We can factor the numerator:
Thus, the expression simplifies to:
Now, we can substitute
into the simplified expression:
Therefore, the limit is:
