Exclusive to AA HL, polynomial functions are studied in depth through their graphs, zeros, roots and factors. Students apply the factor and remainder theorems to factorise and solve polynomial equations, and use the sum and product of roots relationships. Cubic and quartic functions are sketched and analysed, and complex roots of polynomial equations with real coefficients are addressed, linking directly to the complex numbers subtopics.
