Homework Statement
Find the general solution using the method of variation of parameters of:
y''-6y'+9y=(x^-3)(e^3x)
I found the roots of the corresponding homogeneous equation to be lamba = 3. So there are repeated roots. My question is, how do I solve a variation of parameter question with repeated roots? I know how to do it using reduction of order but confused on variation of parameters
