Important Terms Related to Quadratic Equations

1. Quadratic Equation: An equation of the form ax² + bx + c = 0, a ≠ 0 is called a quadratic equation in one variable x, where a, b and c are constants. For example 2 x² – 3x + 1 = 0
2. Roots of a Quadratic Equation: Let ax² + bx + c = 0, be a quadratic equation. If α is a root of this equation. It means x = α satisfies this equation i.e., aα² + bα+ c = 0.
3. Discriminant: For the quadratic equation ax² + bx + c = 0 the expression is called the discriminant and denoted by D. Then the roots of the quadratic equation are given by (–b ± √D)/2a.




Points to be Remembered

I. Number of Roots: A quadratic equation has two roots, one roots or no roots, it is depending the value of D.
1. If D > 0, it has two distinct real roots.
2. If D = 0, it has two equal roots.
3. If D < 0, there is no real roots. II. Methods for Solving Quadratic Equation 1. By factorization 2. By completing the square 3. By Quadratic Formula III. Quadratic Formula to find roots of ax² + bx + c = 0 is given by x = (– b – √D)/2a and x = (– b + √D)/2a.
