Best ResponseYou've already chosen the best response.0you have to asign the equation a characteristic polynomial: for example: 2 d2y/dx2 + 4 dy/dx + 6 = 0 2 m2 + 4m +6 =0 and then you solve the equation for m, you'll have two solutions since it is a second order polynomial: if m1 = m2 the solution, will have the form Ae^m1*x + Bx e^m1*x if m1 is different to m2 and both solutions are real, the solution will have the form A e^m1*x + B e^m2*x if m1 is different to m2 and they both are complex numbers, you use the same form as if they were real numbers, but then you'll have to apply the euler's formula
