## Homework Statement

d4y/dx4 - a4y = eax

I have found the complimentary to be

Y(x)c = C1eax + C2e-ax + C3Cos(ax) + C4Sin(ax)

I can't seem to get get the particular. I've tried letting Y(x) = Aeax

## The Attempt at a Solution

That gives me Aa^4exp(ax) - Aa^4exp(ax) = exp(ax) :(

Try Y=Ctexp(ax).

edit: "t" is a typo: It should be Y= Cxexp(ax)

ehild means $xe^{ax}$, not $te^{ax}$.
