Topics in Quadratic Equations

1

Definition and Standard Form

  • A quadratic equation is an equation of the form ax² + bx + c = 0, where a, b, c are real numbers and a ≠ 0
  • The term 'quadratic' comes from the Latin word 'quadratus' meaning square
  • If a = 0, the equation becomes linear, not quadratic
2

Methods of Solving Quadratic Equations

  • Three main methods: Factorization, Completing the square, Quadratic formula
  • Factorization works when the quadratic can be expressed as product of linear factors
  • If ax² + bx + c = (px + q)(rx + s), then roots are x = -q/p and x = -s/r
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

Real-Life Applications

  • Area problems often lead to quadratic equations
  • Motion problems involving distance, speed, and time
  • Profit and loss problems in business mathematics
