Week Five - Mane 17th Mei

Today we looked at combining the skills of expanding and simplifying into one problem. In order to do this we take the following steps.

  1. Re-write the equation using a multiplication symbol right before the brackets. e.g 7(p + 2) - 4p = 7 x (p + 2) - 4p
  2. Find the part that needs expanding. Shown in bold here: 7 x (p + 2) - 4p
  3. Expand as usual, while leaving the rest the same: 7p + 14 - 4p
  4. Simplify using like terms: 3p + 14
Homework: 9.03

Remember your lines if you need them.
