Diagram illustrating different types of polynomials based on the number of terms: monomial, binomial, trinomial, and four-term polynomial.
A diagram showing polynomial types: Monomial (one term, e.g., -7x⁵), Binomial (two terms, e.g., x² + 9), Trinomial (three terms, e.g., 2x - 4 + 6x⁵), and Four-Term Polynomial (four terms, e.g., -2a² + 3b - 7b³ + 9).
