Y = 4(-3) + 11
y = -12+11
y= -1
so y=4x+11
By letting
we get derivatives
a) Substitute these into the differential equation. After a lot of simplification, the equation reduces to
Examine the lowest degree term , which gives rise to the indicial equation,
with roots at r = 0 and r = 4/5.
b) The recurrence for the coefficients is
so that with r = 4/5, the coefficients are governed by
c) Starting with , we find
so that the first three terms of the solution are
The anwser is 4.4 because you add 9+15 then add 3+2 then divied them both and thats your anwser
