The field strength H of a magnet at a point on the axis at a distance x

Question:

The field strength H of a magnet at a point on the axis at a distance x from its centre is given by

H= M 1 21 [(x-1) 1 (x+ 1) ]

where 2l is the length of the magnet and M is its moment. Show that if l is very small compared with x then

H 2M x 3
