Explanation:
The lens equation states that:

where
f is the focal length
p is the distance of the object from the lens
q is the distance of the image from the lens
For a diverging lens, the focal length is negative: 
and we also know that the object is placed a distance of twice the focal length, so 
So we can find q from the equation above

And the magnification of the image is given by
