Here is the code which I am trying to use in wolfram 9.0.1 mathematica. It wont yield the correct answer. Does anyone see the problem?
Wronskian[x^3*y'''[x] + 12 x^2*y''[x] + 25 x*y'[x] - 25 y[x] == 0, y,x]
If you want to know, here's the ORIGINAL differential equation that I'm trying to solve for.
x^3y''' + 12x^2y'' + 25xy' − 25y = 0; x, x^−5, x^−5 ln x, (0,infinty)
