Subject outcome 2.1: Work with algebraic expressions using the remainder and the factor theorems

Learning outcomes

  • Use and apply the remainder and the factor theorem.
    • Find the remainder.
    • Prove that an expression is a factor.
    • Find an unknown variable in order to make an expression, a factor or to leave a remainder.
  • Factorise third degree polynomials including examples that require the factor theorem
    (long division or any other method may be used).
