Try FOIL For Yourself

[Page 12 of 23]

Click on the appropriate oval to pick an answer, then click Continue.


For which of the following values of m is the above expression positive?

   1

   0

   -1

   -3

   -5

There are several ways to solve this problem, but the quickest is to use reverse FOIL to see that:

Now we can substitute values for m into a relatively simple expression. Let's start with the first choice since it's an easy number to substitute.

Remember, zero is neither positive nor negative, so a result of zero doesn't give us a positive number. Try the next choice.

Not that one, either. What about the next one?

Nope. The fourth choice?

It must be the last choice.

That’s positive, so -5 is our answer.
