Semiconductor problem - Rearranging terms.

In summary, the conversation discusses determining values for the constant of proportionality, beta, for a semiconductor. The student is struggling with understanding the solution and is looking for clarification on the missing squared exponential term. The expert points out that there is no squared exponential term, but rather an exponential term multiplied by its inverse, which equals one. The student expresses gratitude for the clarification.

Im struggling with line 2 to line 3 of the solution. The problem I'm having is I can't see where the squared exponential term has gone. I've tried multiplying out beta and collecting terms in terms of the exponential term, but I'm stuck with the squared expontntial term that would be there. Any ideas on what he has done would really help at this point.

I don't see any squared exponential. I see exp(k) times exp(-k) which is one.
