Factor the given expressions by grouping as illustrated in Example 10. a 2 + ax ab bx Data
Factor the given expressions by grouping as illustrated in Example 10.
a2 + ax − ab − bx
Data from Example 10
Factor: 2x − 2y + ax − ay.
We see that there is no common factor to all four terms, but that each of the first two terms contains a factor of 2, and each of the third and fourth terms contains a factor of a. Grouping terms this way and then factoring each group, we have
I am a tutor in Mathematics subject. I love learning and teaching too. I understand that each student is unique and hence I need to change myself - while communicating with each one of the students - so as to make the activity of learning a play thing, once and then for ever!
I believe in activity-based learning, with the help of tools/games/students participating in events- especially outdoor ones. I also believe in continuous learning and teaching to keep myself up to date!
