Learning Objectives

  • Solve linear and quadratic equations using various algebraic methods (factorisation, completing the square, quadratic formula).
  • Understand and use the discriminant of a quadratic equation to determine the nature and number of its real roots.
  • Interpret the roots, intercepts, and turning points of quadratic functions graphically.
  • Solve simultaneous equations involving two unknowns (linear/linear and linear/quadratic systems) algebraically and understand their graphical interpretation.
  • Solve equations involving absolute values by considering cases or graphical methods.
  • Solve irrational equations (containing square roots) by appropriate manipulation, ensuring to check for extraneous solutions.
  • Solve some higher-order polynomial equations that are reducible to quadratic form or can be factorised.
