The document discusses polynomials and their factoring. It defines polynomials as expressions with real number coefficients and positive integer exponents. Polynomials can be factored by finding common factors. The most common polynomials are trinomials and binomials, which have three and two terms respectively. Examples of polynomial and non-polynomial functions are provided. The shape of polynomial graphs changes as the degree or leading coefficient changes. Key terms discussed include degree, leading coefficient, factored form, and standard form.
