About Course
In Edexcel A-level Mathematics, the study of quadratics is an important component within the broader algebraic curriculum.
Core Concepts:
Quadratic Equations:
Quadratic equations are second-degree polynomial equations
Solving Quadratic Equations:
Methods such as factorization, completing the square, and using the quadratic formula are used to find solutions.
Quadratic Functions:
Quadratic functions are polynomial functions of degree 2. They often describe the shape of a parabola.
Graphs of Quadratic Functions:
The graph of a quadratic function is a parabola with specific characteristics such as the vertex, axis of symmetry, and direction of opening.
Advanced Concepts:
Discriminant:
The discriminant is a value used to understand the nature of solutions to a quadratic equation.
Roots and Zeros:
Roots are solutions to a quadratic equation, and zeros refer to the x-values where the graph intersects the x-axis.
Quadratic Inequalities:
Quadratic inequalities involve the relationship between quadratic expressions and play a role in understanding graphed regions.
