Understanding Quadratic Equations

A quadratic equation is a polynomial equation of the second degree. The general form is ax² + bx + c = 0, where a, b, and c are constants, and 'a' is not zero. The solutions to these equations are called roots, which represent the x-intercepts of the parabola described by the equation. The discriminant (Δ = b² - 4ac) determines the nature of the roots: if Δ > 0, there are two distinct real roots; if Δ = 0, there is one real root (repeated); and if Δ < 0, there are two complex roots. The quadratic formula, $$ x = \frac{-b \pm \sqrt{b^2-4ac}}{2a} $$, is used to find these roots. Quadratic equations are fundamental in various fields like physics, engineering, and economics for modeling parabolic trajectories, curves, and optimization problems.
