Algebra Worksheet 1 – Scaffolding Learning using BYOD
Factorising Algebraic Expressions using Mathway on BYOD
On your device google ‘Mathway’ and once you are on the webpage, click on
Algebra. Type in your expression, for example, 12k+15ky.
Next click on ‘find the HCF’ and what’s given is the Highest Common Factor, 3k
which is part of your answer.
In your books, write 12k+15ky = 3k(
). Now try and complete what is
inside the bracket. Check your answer by clicking on ‘Factor’ from the list of
options and then click on answer and what is shown is 3k(4+5y).
Now factorise the following by clicking on ‘find the HCF’ first and then ‘factor’.
Once you have factorized a few expressions this way, you may want to write
the full answer on your own and click on ‘factor’ in Mathway to check!
