Rational Roots Theorem - Concept

Concept Concept (1)

The rational roots theorem states that all potential roots are in the positive or negative form of the last coefficient s factors divided by the first coefficient s factors. With a large polynomial, solving by factoring is more difficult, and so finding the rational roots will give some potential zeros to start with. With these rational roots, the solutions after factoring complicated expressions is narrowed down to a select few answers.
