# A-Level Maths Resources for Teachers and Students

## Syllabus • Algebra and Functions

Laws of indices for all rational exponents. Use and manipulation of surds. Students should be able to rationalise denominators. Quadratic functions \(ax^2+bx+c\) and their graphs. The discriminant of a quadratic function. Completing the square. Solution of quadratic equations. Solution of quadratic equations by factorisation, use of the formula and completing the square. Simultaneous equations: analytical solution by substitution. For example, where one equation is linear and one equation is quadratic. Solution of linear and quadratic inequalities.
