A quadratic equation is a second-degree algebraic equation typically expressed as ax^2+bx+c=0, where x is the unknown, and a, b, and c are constants. Quadratic equations can be solved using either factorization or the quadratic formula.

A quadratic equation is a second-degree polynomial that models the behavior of many physical, biological, and social systems.

The quadratic equation is a type of algebraic equation that either has a positive or negative root. This equation is used in mathematics and engineering as a way to describe some phenomena. The quadratic equation arises often in the study of fractals, electromagnetism, fluid dynamics, telecommunications systems, and quantum mechanics. In these fields, the solution to the quadratic equation allows one to estimate some unknown quantities.

The quadratic equation is an indispensable tool in many disciplines, including physics and engineering. In physics, the quadratic equation can be used as a model to predict the motion of objects that follow a parabolic path with gravity as the only force involved.
