Quadratic Equations - Formulas, Methods, and Examples - Cuemath
A quadratic equation is of the form ax^2 + bx + c =0, where a, b, and c are real numbers. The most popular method to solve a quadratic equation is to use a quadratic formula that says x = [-b ± √(b2 - 4ac)]/2a.
2.5: Quadratic Equations - Mathematics LibreTexts
The quadratic formula not only generates the solutions to a quadratic equation, it tells us about the nature of the solutions when we consider the discriminant, or the expression under the radical, \(b^2−4ac\). The discriminant tells us whether the solutions are real numbers or complex numbers, and how many solutions of each type to expect.
