Key Topics to Revise

1

1. Meaning and Standard Form

  • A quadratic polynomial equated to zero gives a quadratic equation.
  • The standard form is ax^2 + bx + c = 0, with a ≠ 0.
  • Any equation of degree 2 written in descending order can be written in this standard form.

2. Formation of Quadratic Equations from Situations

  • Many word problems become quadratic equations after forming expressions for length, breadth, age, number of items, or cost.
  • John's marbles problem leads to x^2 - 45x + 324 = 0.
  • The toys production problem leads to x^2 - 55x + 750 = 0.

3. Checking Whether an Equation is Quadratic

  • Simplify fully before deciding whether an equation is quadratic.
  • Some equations look quadratic but become linear after simplification.
  • Some equations look cubic but simplify to quadratic form.
4

4. Finding Roots by Factorisation

  • Factorisation is a direct method for solving many quadratic equations.
  • Split the middle term and write the quadratic as a product of two linear factors.
  • If a product is zero, at least one factor must be zero.
