Question:medium

The differential equation of the family \( y = a e^{x} + b x e^{x} + c x^{2} e^{x} \) is

Show Hint

A repeated root 'r' of multiplicity 'k' in a linear ODE leads to solutions $e^{rx}, xe^{rx}, ..., x^{k-1}e^{rx}$.

  • $y''' + 3y'' + 3y' + y = 0$
  • $y''' + 3y'' - 3y' - y = 0$
  • $y''' - 3y'' - 3y' + y = 0$
  • $y''' - 3y'' + 3y' - y = 0$
Show Solution

The Correct Option is D
