Multiply the factors.
You may want to use a generic rectangle.
The first row has been filled in for you.
Simplify after multiplying.
Use the same process as part (a).
, and −
What are the factors?
Multiply the last two factors first.
Then multiply the result by (x + 2).
Use the ideas from part (a) and (c) to help you.
How can you use the results from part (a) to make this problem easier?
