(x+17)(x-20)(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.

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.

{x straight up and down line-17<x<-8 or x>20}
