Question:computing the wronskian with Maple gave nothing

I am tying to compute the wronskian of a fourth order DE: y=C₁e^2x+ C₂e^-x +C₃xe^-x+ C₄x²e^-x Here's what I did:

with(VectorCalculus):
with(LinearAlgebra):

Determinant(Wronskian([e^(2*x), e^(-x), xe^(-x), x^2*e^(-x)], x)):

which gave nothing.
Can anyone please help?

Thanks in advance,
