First we'll take the case of concave mirror..
the mirror formula is.......1/f = 1/v + 1/u.
in our case u = -15cm
                  f = -10cm
therefore  1/-10 = 1/-15 + 1/v
               1/v = 1/-10 + 1/15
                 v = -30
magnification formula is -v/u
.....................30/-15
the object is magnified with a factor of -2
the image formed is real inverted, magnified.
