The document discusses using the factor theorem to factor polynomials. It provides examples of finding the factors of a polynomial given its zeros. It also presents the factor-solution-intercept equivalence theorem, which states that for any polynomial f, the following are equivalent: (x - c) is a factor of f, f(c) = 0, c is an x-intercept of the graph y = f(x), c is a zero of f, and the remainder when f(x) is divided by (x - c) is 0. Examples are worked through to demonstrate factoring polynomials by finding zeros and dividing.
