Q18 of 29 Page 1

Can y = ax + be a solution of the following differential equation?


If no, find the solution of the D.E. (*).


OR


Check whether the following differential equation is homogeneous or not



Find the general solution of the differential equation using substitution y=vx.


Given,



If, it should satisfy the above equation


Taking RHS of (*)





= y


= LHS


Hence, is a solution of DE(*)


OR



[1]


Now,



Now, for equation to be homogenous, f(x, y) should be homogenous


i.e.


f (zx, zy) = znf(x, y)


Now,



≠ znf (x, y) for any n


Hence, the given equation is not homogenous


Now, put y = vx



Therefore [1], becomes











Integrating both sides,



Put
