Completing the Square
Completing the Square is a fundamental algebraic technique used to solve quadratic equations and manipulate quadratic expressions. By transforming a quadratic expression into a perfect square trinomial, this method enables the easy derivation of key properties such as the vertex form of a quadratic function. This process involves adding and subtracting a carefully chosen constant term to both sides of the equation, resulting in a quadratic expression that can be factored into a squared binomial. Completing the Square plays a crucial role in various mathematical applications, including optimization problems and graphing quadratic functions.
