This guide covers the fundamental vocabulary related to polynomials, including monomials, binomials, and trinomials. It explains the concept of like terms, where terms share the same variable and exponent, as well as how to find the degree of a polynomial by identifying the highest degree of its monomials. Step-by-step examples illustrate how to determine if an expression is a polynomial, find its degree, and simplify polynomial expressions. Key examples include combining and simplifying terms for clarity and comprehension.
