The document discusses the relationship between the remainder when dividing a function f(x) by (x-c) and the value of f(c). Specifically, it states that the remainder is equal to the value of f(c), and if the remainder is 0, then (x-c) is a factor of the function. This relationship means that using synthetic division to find the remainder can simplify calculations, as the remainder directly provides the value of the function at that point. The document also includes a lame joke about French fries.
