I think the equation was just rearranged so that you can see where the poles and zeroes are. But the equation does look a little odd to me with the "wz/s" term in the numerator. That just doesn't look right...

It is called an "inverted zero". It is just a simpler way to write the transfer function. The inverted zero is formed by a pole at the origin + a real zero.
 
Thank for reply.

Is there any document available to get familiar with transfer function in depth?

Regards
 

To get familiar with transfer functions in depth, there are books. Microelectronics books generally have a chapter in transfer functions e.g. Sedra and Smith.
