y^{(5)}- 2y^{(4)}+ y^{(3)}= 0

This is 5th-order, linear, HG, with constant coefficients, and hence I used the characteristic equation:

m^{5}- 2m^{4}+ m^{3}=

m^{3}(m - 1)(m - 1) = 0

Hence, m = {1,1,0,0,0} and so the solution is given by:

y(x) = C1 + C2*x +C3*x^{2}+ C4*exp(x) + c5*x*exp(x).

This is the Wolfram solution.

They seem to have an extra exponential term inside of the parentheses. Am I missing something?

Thanks!
