## Homework Statement

Use variations of parameters to find the general solutions of the following differential equations.

y'''''-4y'''=32exp^(2x)

## Homework Equations

no relevant equations.

## The Attempt at a Solution

hey there, I tried solving this question. I got the homogeneous equation.

y

_{h}(x)=C

_{1}+C

_{2}x+C

_{3}X

^{2}+C

_{4}exp^(2x)+C

_{5}exp^(-2x)

but after this step.. I am stuck..

Because I am not quite sure whether I am in the correct path to look for the general solutions. After I have this equation, I did the wronskian matrix, I found the determinant of the 5X5 matrix is 512. Am I correct? Please correct me if I am not in the journey to my answer.

Besides that , If I were to use the variations of parameters. The matrix would be 5X5 dimensions. Is it correct?

Thanksedited due to duplication on the template question.. sorry..
