Quadratic Equations

A quadratic equation is a type of polynomial equation that can be expressed in the standard form: ax² + bx + c = 0, where a, b, and c are constants, and a is not zero. The "x" represents an unknown variable. Quadratic equations can have two solutions, one solution, or no real solutions, which can be found using various methods, including factoring, completing the square, or the quadratic formula. These equations are fundamental in mathematics, appearing in various fields such as physics, engineering, and finance, often modeling phenomena like projectile motion or profit maximization.
