Log in to Manga High  (www.mangahigh.com) and go to 'mytodolist' tab.  Please attempt the following challenges:

  • [Solve quadratics with 2 terms]
  • Factorise using a common bracket
  • Factorise 4 terms into 2 brackets

Note: anything in square brackets [] is optional. You may skip it if you like.  However, it is good practice ;-)
