Homework Help: Solve Inequality

Posted by Armando on Sunday, May 29, 2011 at 3:26pm.

Solve the inequality. Express your solution using interval notation and please show all of your work.
x(x + 6)(8 – x) >= 0

I need help, I guess I'm not understanding the interval notation portion.

I know, that when

0 <= x <= 8
x <= -6

that the statement is true.

but when I got my paper back it said that I got it wrong. I'm guessing that because it is not solve using interval notation, but I'm clueless.
