Homework Statement
[tex]t^{2}[/tex] * y'' - 2y = [tex]3t^{2}[/tex] - 1
[tex]y_{1}[/tex] = t[tex]^{2}[/tex]
[tex]y_{2}[/tex] = 1/t

The Attempt at a Solution
W = t^2 * -t^-2 -[1/t * 2t] = -3
Y = -t^2 * Integral[ (-1/3)(1/t)(3t^2 -1)] + 1/t * Integral[(-1/3)(t^2)(3t^2 -1)]
I get an answer that is not correct so I guess I set this part up wrong somehow anyone see the error?
My answer: Y = 3/10*t^4 - t^2 * ln|t|/3
Correct Answer: Y = t^2*ln|t| + 1/2
