Important Terms Related to Quadratic Equations

  • 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
  • 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.
  • 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.



Must Remember
  • 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.
  • Methods for Solving Quadratic Equation
    1. By factorization
    2. By completing the square
    3. By Quadratic Formula
  • Quadratic Formula to find roots of ax² + bx + c = 0 is given by x = (– b – √D)/2a and x = (– b + √D)/2a.
