Determine order and degree (if defined) of differential equations given in y’’’ + 2y’’ + y’ = 0

The highest order derivative present in the differential equation is  and its order is 3.

The given differential equation is a polynomial equation in derivatives  and  and the highest power raised to highest order  is two, so its degree is 1.

Hence, order is 3 and degree is 1.
