Question 421195
    Make a table to study the sign of the product of linear equations:

       |-2   -1      |17
---|---|------|------|-----
x+2  - 0    + |  +   |   +
---|---|-------------|-----
x+1| - |   -  0   +  |   +
---|---|------|-----------
x-17 - |   -  |    - 0   +
---|---|------|------|----
P. | - |   +  |    - |   +
---------------------------

 Answer: From the table we conclude that for -2 < x < -1 and x > 17 the inequality is satisfy.
