1. The problem statement, all variables and given/known data y''-4y'+4y=(12e^2x)/(x^4) I am trying to solve this differential equation. I know you would use the variation of parameters method, and I am trouble with the wronskian. My solution manual doesn't actually use a wronskian so I can't verify my work 2. Relevant equations 3. The attempt at a solution I end up with w=e^4x w1=(-12e^4x)/(x^3) w2=(12e^4x)/(x^4) But at this point the integrals for u1 and u2 seem rather impossible.
