Topics in Quadratic Equations

1

Basic Concepts and Definitions

  • A quadratic polynomial is of the form ax² + bx + c where a, b, c are real numbers and a ≠ 0
  • A quadratic equation is of the form ax² + bx + c = 0 where a ≠ 0
  • The highest power of the variable x is 2 in a quadratic equation
2

Solving by Factorisation Method

  • Based on the zero product rule: if ab = 0, then a = 0 or b = 0
  • Express ax² + bx + c as a product of two linear factors
  • Set each factor equal to zero and solve
3

Quadratic Formula Method

  • Universal method that works for all quadratic equations
  • Derived by completing the square method
  • Also known as Sridharacharya formula
4

Nature of Roots and Discriminant

  • Discriminant D = b² - 4ac determines the nature of roots
  • Three cases based on discriminant value
  • Helps predict root nature without solving the equation
