Summary

  1. A rational expression has a polynomial in the numerator and denominator
  2. For example, let's have a numerator of '7x+14' and a denominator of 'x2-4'
  3. 'x' is a variable

Notes

    1. You can also think of it as a ratio of two polynomials
    1. 'x' is a variable
    2. Notice that both the numerator and denominator are polynomials
    3. So this is an example of a rational expression
