Solve
(x+17)(x20)(x+8)>0
The solution set is (x )?
Use at least one inequality or compound inequality to express your answer. For answers with more than one inequality, separate the inequalities by a comma or the word 'or'. Type R is the answer is all real numbers. Type N if there is no solution.

Goodness. To be greater than zero, all () have to be positive, or two negative.
If x>17, the first is postive, the second negative until x>20, and the third is negative until x>8.
So the solution for this parenthesis is x is >17 and less than 8.
Try the other two, we will be happy to critique yourthinking.
