A quadratic equation is a polynomial equation of the second degree. The standard form is: x represents an unknown variable. a, b, and c are constants (a ≠ 0). ax² is the quadratic term. bx is the linear term. c is the constant term. 3 Core Methods to Solve Quadratic Equations

This method involves transforming the equation into a perfect square trinomial. It is particularly useful for deriving the quadratic formula itself and for graphing parabolas. Understanding the Discriminant A quadratic equation is a polynomial equation of
The term under the radical in the quadratic formula () is called the discriminant (D) . It tells you the nature of the roots: D > 0: Two distinct real roots. D = 0: One real root (a repeated root). D < 0: Two complex (imaginary) roots. Real-World Applications Why learn this? Quadratic equations are used to:
This method involves breaking the equation down into two linear expressions. Example: x² + 5x + 6 = 0 becomes (x + 2)(x + 3) = 0. Roots: x = -2, x = -3. 2. The Quadratic Formula ax² is the quadratic term
There are several ways to find the "roots" (the values of x that make the equation true). Our downloadable PDF covers these in detail with step-by-step examples. 1. Factoring
