Question

Use this approach to find the given question ans is root 2 use this approach u will get solution do handwritten only I'll rate 

what is the radius of convergence of the taylor series for (x2-2x+2)-1 about x=0
(x2 – 2x + 2)-1
Concept
Radius ols convergence el Taylos series for (oe²-2<+3)+
about =o
is the radius odk the biggest cixele that
can be drsaun Anking (0,0) as the center of the circle
so that there be no amy
point inside the cirele
where (x?-2x+3)-1 is not analy tical.
We have,
つc2-2243
We know that denominator should nit be equal to zero.
