Algebra II is a high school mathematics course that builds on concepts learned in Algebra I. It typically covers advanced topics such as quadratic equations, polynomials, rational expressions, and functions. Students also explore complex numbers and learn how to solve systems of equations and inequalities. In addition to these topics, Algebra II introduces students to exponential and logarithmic functions, as well as sequences and series. This course is essential for preparing students for higher-level math courses, such as Pre-Calculus and Calculus, and is often a requirement for college admission.
