The general solution of the differential equation ( y'''' - 3y''' + 3y'' - y' = 0 ) can be found by solving the characteristic equation associated with the differential equation.
The characteristic equation is obtained by substituting ( y = e^{rx} ) into the differential equation, which yields ( r^4 - 3r^3 + 3r^2 - r = 0 ).
Factoring out ( r ), we get ( r(r^3 - 3r^2 + 3r - 1) = 0 ).
This equation can be further factored into ( r(r - 1)^3 = 0 ).
The roots of this equation are ( r = 0 ) (with multiplicity 1) and ( r = 1 ) (with multiplicity 3).
Thus, the general solution of the differential equation is ( y = C_1 + C_2e^x + C_3xe^x + C_4x^2e^x ), where ( C_1, C_2, C_3, ) and ( C_4 ) are arbitrary constants.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
