I don't think decompose it the word you want.

CPhill has factorised your expression.  

that is, the factors of x29 are  x3 and x+3   so

x29=(x3)(x+3)

 

x29 is the difference (take away) of two squares   x squared and 3 squared

x29=x232 but it is quite the simplest form

x^2 - 9  =

(x + 3) (x - 3)
