What is the difference between the energy of spring a, stretched 0.6 meters, and spring b, stretched 0.3 meters, if they have the same spring constant?

What is the difference between the energy of spring a stretched 06 meters and spring b stretched 03 meters if they have the same spring constant class=

delE = 1/2 k (dX^2 - dx^2); where dX = .6 m and dx = .3 m.  

So we need k, the constant, to get the "difference."  

But I'm guessing you really want E/e = 1/2 kdX^2/1/2 kdx^2 = (dX/dx)^2 = 4 so E = 4e, which is to say spring A has 4 times more energy than B. ANS.

Spring A has more potential energy than spring B.
