Question 365387: Hello, I'm working on some practice problems and checking my work with you. I thought I understood this material and just got a 4 out of 10 on my quiz! Ouch.
Using the rational zero test, I must find all possible rational roots:
3x%5E3+%2B+3x%5E2+-+4x+-+9
First I identified the constant (-9) and the leading coefficient (3) and then I listed the factors of each:
-9: 1, 3, 9
3: 1, 3
Then I divide all factors of the constant by the factors of the leading coefficient:
1%2F1, 1%2F3, 3%2F1, 3%2F3, 9%2F1, 9%2F3
My final answer is 1, 1%2F3, 3, and 9
Thanks in advance for your valuable time! :)

That's 1/2 of the answer, you also need -1,-1%2F3,-3, and -9.
