Rational functions are quotients of polynomials. In such cases, the polynomial will not factor into linear polynomials. Polynomials with rational coefficients always have as many roots, in the complex plane, as their degree however, these roots are often not rational numbers. In such cases, the polynomial is said to "factor over the rationals." Factoring is a useful way to find rational roots (which correspond to linear factors) and simple roots involving square roots of integers (which correspond to quadratic factors).
