Things I have learned:

-Factoring polynomial expressions:
I did some simple questions

e.g.

The first one what I did was finding the greatest common factor that the equation has, which is 4. The second one is same as the first one, and the greatest common factor is .

Here is another example I found in the internet:

For this example, 3 is the greatest common factor.

Even though these questions are not new for me, it still helps me. I didn’t do factoring for a while, so these questions allow me to practice more. I have to find the GCF in each question, it is similar to Chapter 1 (Number), it’s pretty much the same thing.
