Quadratic Equations
A quadratic equation is a second-degree polynomial written in the form of ax² + bx + c = 0, where a ≠ 0. It is used to solve problems involving area, velocity, and motion paths. For example, it is used to calculate the area of different shapes, the velocity of moving objects, and the trajectories of objects following parabolic paths, such as projectiles. The solutions to a quadratic equation are the points where its parabola-shaped graph crosses the x-axis. These solutions are called roots or zeros.
