The order of the differential equation of all parabolas, whose latus rectum is 4a and axis parallel to the X-axis, is 

Answer:

Explanation:

Equation  of all parabola , whose axis is parallel  to X- axis  and have latusrectum 4a , is (y-K)²  =4a(x-h)²

Here, we have two effective constants, K  and h. So, we have to differentiate it twice.

 Hence, the order of the differential equation is 2
