Second order non homogeneous ODE, IVP

Click For Summary
SUMMARY

The discussion focuses on solving the second-order non-homogeneous ordinary differential equation (ODE) given by x²y'' - 4xy' + 6y = x³ with initial conditions y(1) = 3 and y'(1) = 9. The correct solution is identified as y = x² + 2x³ + x³lnx. Participants confirm that the method of variation of parameters is applicable for finding a particular solution, and an alternative method using undetermined coefficients is also suggested. A resource link is provided for further understanding of constructing particular solutions.

PREREQUISITES
  • Understanding of second-order ordinary differential equations (ODEs)

The Attempt at a Solution

I know that the answer is: y=x^2+2x^3+x^3lnx
Where did I go wrong. I was wondering if it's even logical to solve it as an Euler Cauchy and then use variation of parameters...
