## Homework Statement

I am trying to understand how some equations are obtained in some lecture notes I have.

This is my starting equation-http://i423.photobucket.com/albums/pp315/skaboy607/StartEquation.png

And I need to satisfy these conditions

## Homework Equations

all above

## The Attempt at a Solution

I've stared at it for a while now and just don't get it. Wouldn't the square come down in front of the brackets? and surely the other constants would dissapear?

any help most appreciated..

Thanks
