Determine the order and degree(if defined) of the differential equation  y'+ y = ex.

order =2, degree= 1. order =1, degree= 2. order =1, degree= 1. none of these.

order =1, degree= 1.

he highest order derivative present in the given differential equation is y'. Therefore, its order is one. The given differential equation is a polynomial equation in  y'. The highest power raised to y'' is one. Hence, its degree is one.
