The following are examples of rational expressions: The last example, 6 x + 5, could be expressed as Therefore, it satisfies the definition of a rational expression. First of all, we can factor the bottom polynomial (it is the difference of two squares): x−1(x+3)(x−3). Now we can see: The roots of the top polynomial are: +1 (this is where it crosses the x-axis) The roots of the bottom polynomial are: −3 and +3 (these are Vertical Asymptotes) It crosses the y-axis when x=0, so let us set x to 0.
