8-87.

For each of the following sets of numbers, find the equation of a function that has these numbers as roots.

and If these are the roots, what are the factors?

Multiply the factors.

You may want to use a generic rectangle.

The first row has been filled in for you.

Simplify after multiplying.

and Use the same process as part (a).

−2,

, and − What are the factors?

Multiply the last two factors first.

Then multiply the result by (*x*+ 2).

and 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?
