Topics in Quadratic Equations

1

1. What is a Quadratic Equation?

  • A quadratic equation in variable x is of the form ax² + bx + c = 0, where a, b, c are real numbers and a ≠ 0.
  • The word 'quadratic' comes from the Latin word 'quadratus' meaning square.
  • The highest power of the variable must be 2 for it to be quadratic.

2. Solving by Factorisation

  • Factorisation means expressing ax² + bx + c as a product of two linear factors.
  • The method is based on the Zero Product Property: if P × Q = 0, then P = 0 OR Q = 0.
  • To split the middle term: find two numbers p and q such that p + q = b and p × q = a × c.

3. Solving by Completing the Square

  • This method converts ax² + bx + c = 0 into the form (x + k)² = d, which is easy to solve.
  • First, make the coefficient of x² equal to 1 by dividing throughout by a.
  • Then, add and subtract (b/2a)² to complete the perfect square.

4. The Quadratic Formula

  • The quadratic formula gives roots of ax² + bx + c = 0 directly using the values of a, b, and c.
  • Formula: x = (-b ± √(b² - 4ac)) / 2a
  • This formula is applicable for ALL quadratic equations — it never fails.
