Using perfect squares simplification, it is found that the value of the desired limit is of -4.
<h3>When is a limit?</h3>It is the value of a function as x approach
In this problem, the limit we want to find is given by:
If we just replace x by -2, we end with an undetermined limit, as we have 0/0.
However, the perfect square simplification states that:
a² - b² = (a - b)(a + b).
Hence:
x² - 4 = (x + 2)(x - 2).
Then:
Hence, the value of the desired limit is of -4.
