Order: Order of a differential equation is the order of the highest order derivative (also known as differential coefficient) present in the equation
Degree: The degree of the differential equation is represented by the power of the highest order derivative in the given differential equation.
Hence the degree of the given differential is
2
and the order is also
2.
