(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I am asked to determine two shape functions based off of a polynomial and Boundary conditions that are given at this url: http://i267.photobucket.com/albums/ii286/TechNewsSource/ShapeFunctions.jpg" [Broken]

I would have posted it here but I can't remember how to do symbols on forums.

3. The attempt at a solution

Anyways, using the prescribed boundary conditions, which are the result of a beam fixed at both ends, I couldn't determine what to use for the two shape functions. I know that using x/L and (x/L)^2 would be valid shape functions, but I am not sure how to determine the shape functions based off of the given polynomial. I am sure it is something simple I am missing, but I just couldn't figure it out. Any help is greatly appreciated. Thanks
