Key Topics to Revise

1

Standard Form and Basic Concepts

  • A quadratic equation is an equation involving one variable with maximum power 2
  • General form: ax² + bx + c = 0, where a, b, c are real numbers and a ≠ 0
  • The term 'a' is coefficient of x², 'b' is coefficient of x, and 'c' is the constant term
2

Methods of Solving Quadratic Equations

  • Factorization method: Express as (x - α)(x - β) = 0
  • Completing the square: Convert ax² + bx + c into perfect square form
  • Quadratic formula: Universal method that works for all quadratic equations
3

Nature of Roots and Discriminant

  • Discriminant Δ = b² - 4ac determines the nature of roots
  • If Δ > 0: two distinct real roots
  • If Δ = 0: two equal real roots (repeated root)
4

Relationship Between Roots and Coefficients

  • Sum of roots: α + β = -b/a
  • Product of roots: αβ = c/a
  • These relationships hold regardless of the method used to find roots
