# Math Help - Is an exponential solution the correct thing to try here?

1. ## Is an exponential solution the correct thing to try here?

Hi all,

I have an ODE of the form X" + aX' + (bc)^2 X = 0.

Is the correct way of solving this to try an exponential solution of the form Ae^rx?

2. Assuming a,b, and c are constant it could be of this form, have you solved your charateristic equation yet? What did you get?

3. Yes, a,b and c are constants, sorry I forgot to put that in.

r^2 + ar + (bc)^2 = 0.
