Homework Statement



x2y"-(x2+2x)y'+(x+2)y=0

known solutions:

y1(2)=2
y1'(2)=1
y2(2)=2e2
y2'(2)=3e2

Determine the wronskian

Homework Equations



yc=C1er1x+C2er2x

I also know how to find the wronskian via a determinant

The Attempt at a Solution



I have tried to divide out the first x2 term to make this a linear system, not sure how to simplify after this to find the characteristic solution.

I found the answer using Abel's theorem.
 
nvm: I see you found your answer.

Isn't the complementary general solution equations you provided for differential equations with constant coefficients, rather than coefficients that are functions of a variable?

you are correct. I was confused with the question and obviously drew a blank.
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
