What is a quadratic equation?

A quadratic equation is a polynomial equation of the form ax^2 + bx + c = 0, where x represents an unknown variable, and a, b, and c are constants with a not equal to 0. The highest power of x in a quadratic equation is 2, hence the term "quadratic." Quadratic equations can have one, two, or no solutions, depending on the values of a, b, and c. These equations are commonly used in algebra to solve a variety of problems, such as finding the roots of a function or determining the maximum or minimum values of a quadratic expression.
