Remember Cedric. Remember, if the time should come when you have to make a choice between what is right and what is easy, remember what happened to a boy who was good, and kind, and brave, because he strayed across the path of Lord Voldemort. Remember Cedric Diggory.

Hi ash,
its like this
taking derivative wrt x we get,
b=(dy/dx-2y)e^-2x
now put this value in the eq of second order derivative to get
d^2y/dx^2 = 4dy/dx -4y
hope u got it
