The order of the differential equation whose solution is x2+y2+2gx+2fy+c=0
1
2
3
4
Explanation for the correct option
Given equation is x2+y2+2gx+2fy+c=0
There are 3 arbitrary constants g,f and c
Therefore the order of the differential equation is 3
Hence, the correct option is C.
The order of the differential equation whose solution is , is
