1. You have to find the radius <span>of convergence of the following Maclaurin series:
</span>

2. Let's take the denominator and find the roots:

3. The roots are

and the distance from the origin is

.
Therefore, the answer is:
By definition of absolute value, if
, then
, so

On the other hand, if
, then
, and
