Task goals

  • Find the highest common factor of algebraic terms and factor it out to write expressions in the form $a(bx+c)$.
  • Use division to extract the common factor, then check by expanding back to the original form.
  • Apply factorising to expressions with letter factors, negative terms, and multiple terms inside the bracket.
