Multiplying Polynomials: Day 2

Multiplying Polynomials - Day 2

Homework:

As I said in the video, complete the 4 highlighted questions on a separate piece of paper, then submit them to google classroom.

You may head out. Have a great day! :)

During this Activity:

• Watch all the videos fully.

• Take notes on the videos in your math notebook.

• Answer all the questions.

• If you complete the activity, you may start your homework!

• If you need any help, hit the "Ask for Help" button on the Zoom bar in your breakout room.
