Answer:
R1= 10.04
R2=10
Step-by-step explanation:
The differential equation is given by:

The minimum radius of convergence is given by the distance from the point x=a, to the nearest singularity points of the differential equation.
The singularity points are the roots of the polynomial that multiplies the second derivative of y. Thus, you have:

the roots are in the complex plane. The radius of convergence is the distance between the points z1=0+0i, z2=1+0i (x=0 and x=1, respectively), in the complex plane, that is:

Answer:
26.74
Step-by-step explanation:
(12.95x2)+35.89+11.47=73.26
100-73.26=26.74
