The document discusses key concepts related to polynomials. It defines a polynomial as an expression composed of variables, constants, and exponents combined using mathematical operations. The degree of a polynomial is defined as the highest degree of any monomial term within the polynomial. For example, the degree of the polynomial x5+x3+x2+1 is 5. Terms of a polynomial are the parts separated by addition or subtraction operators, like the four terms in the polynomial 2x3 - 4x2 + 7x - 4. Factors of a polynomial are any polynomials that divide evenly into the original polynomial. Zeros of a polynomial are the values of x that make the polynomial equal to 0.
