Essentially, non-linear terms are written in fractional form. When the same letter is present in both the numerator and the denominator, it is possible for the letters to divide themselves out of the expression, and leave simply a constant term. 

This video lesson will discuss two steps in the process. First, determine the value of K, and second, use the general term to find the constant.

If you haven’t yet seen the initial lesson on the Binomial Theorem, it would be a good idea to check it out first.
