Given an ODE of the form

a regular singular point

is one such that

or

diverge as

, but the limits of

and

as

exist.
We have for

,

and as

, we have

and

, so indeed

is a regular singular point.
We then look for a series solution about the regular singular point

of the form

Substituting into the ODE gives




From this we find the indicial equation to be

Taking

, and in the

term above we find

. So we have

Since

, all coefficients with an odd index will also vanish.
So the first three terms of the series expansion of this solution are

with

,

, and

.

Answer:
3
Step-by-step explanation:
4 - 1 = 3 Therefore, Sarah bought 3 more pounds of peaches then she did apples.
<span>f(x)= 50x
</span><span>y = k x
k is variation
so k= 50
D is the right option
