A quadratic equation is a second-degree polynomial equation in a single variable, typically written in the form “ax^2 + bx + c = 0,” where “a,” “b,” and “c” are constants, and “x” represents the variable.
Quadratic equations often yield two solutions, known as roots or solutions, which can be real or complex numbers.
They are fundamental in algebra and are used to model various real-world phenomena, such as the trajectory of projectiles, the shape of parabolic curves, and optimization problems in mathematics and physics.
