Unit 6-Objective 3- Factoring by Grouping


can be factorized if you group the 1sttwo terms together and the 3rd and 4th terms together.
The 1st two terms are the difference of two squares.

You can now group the terms like this:

and you can factor out (2p+q)

Another example

If you group the 1st two terms together and the 3rd and 4th
terms together you can factorize:
(Notice that (2-y) and (y-2) are not the same so
you need to factor out )

(You can use distributive property to check your answers)
You can rewrite the problem

You can now factor out the quantity (2-y)

Now you can factor out y also.
