i wanted to know how to do it though but i'll just work backward

You can use the rational zero theorem, where you look at your last term and your first term, so we have \[\frac{ \text{factors of 20} }{ \text{factors of 1} }\]
I think that's a pretty easy way to do it :), so list your factors but remember there are positive and negative terms.
So since it's a polynomial we can treat the first term as P and last term as Q\[\frac{ P }{ Q } = \frac{ \text{factors of 20} }{ \text{factors of 1} }\] so just a nicer way of putting it.
So what are the factors of 20?
20 and 1, 2 and 10, 4 and 5
come on human calculator XD
Factors of 20 are 1,2,4,5,10,20 so you got that :) now what are the factors of 1
1
But remember it's positive and negative!
so 1 and 1, -1 and -1
So we have \[\frac{ P }{ Q } = \pm \frac{ 1,2,4,5,10,20 }{ 1 } = \pm 1,2,4,5,10,20 \] :)
Easy peasy right?
yup. Is that positive negative for all of them?
so the answer is c, right?
Yup! This \[\pm \] indicates it has a positive value and negative, and yup that sounds good!
i fanned you, you are awesome!
Haha, thanks! It's always fun to learn with people!
