This is similar to Problem 4 from your Section 2.2 worksheet.

By setting up an appropriate inequality and solving it, determine for what values of the expression will be (a) positive, (b) negative, and (c) zero. Write your solution in interval notation. If an interval uses infinity, type "INF".

a) will be POSITIVE for values of in the interval

b) will be NEGATIVE for values of in the interval

c) will be ZERO for values of in the interval
