Topics in Quadratic Equations

1

1. What is a Quadratic Equation?

  • A polynomial of degree two is called a quadratic polynomial.
  • When a quadratic polynomial is equated to zero, it becomes a quadratic equation.
  • A quadratic equation is studied in one variable.
2

2. Standard Form and Rewriting Equations

  • A quadratic equation in standard form is ax^2 + bx + c = 0.
  • The equation can be rewritten from any valid quadratic form into standard form.
  • In the definition section, a > 0 is stated; later formula tables and key points state a != 0.
3

3. Roots or Solutions

  • The value of the variable for which the left-hand side and right-hand side of the equation become equal is called a root or solution.
  • The zeroes of a quadratic polynomial are the roots of the corresponding quadratic equation.
  • A quadratic equation has at most two roots.
4

4. Factor Method

  • The factor method solves a quadratic equation by factorising it into linear factors.
  • After factorisation, each factor is set equal to zero.
  • This method works well when the equation can be factorised easily.
