Question

The differential equation of all conics with the coordinate axes, is of order

1
2
3
4

Hint:

In this question we have to find the order of the differential equation of all conics with the coordinate axis. First we will find the differential equation by differentiating the equation twice then we will get the order.

The correct answer is: 2
