Best ResponseYou've already chosen the best response.2The possible rational roots are the factors of the constant term which is 10 divided by the factors of the coefficient of the term with the highest exponent which is the x^3 term. It's coefficient is 1. So the possible rational roots are: \[\frac{\pm10}{1}, \frac{\pm5}{1}, \pm\frac{2}{1}, \frac{\pm1}{1}\]

Best ResponseYou've already chosen the best response.2Use synthetic division to see if any of those are actually roots.

Best ResponseYou've already chosen the best response.2Since we have reason to believe that 2 is a root, let's try it.

Best ResponseYou've already chosen the best response.2So we see that 2 is a root and now we must solve the quadratic equation x^24x+5=0 to find the other roots.

Best ResponseYou've already chosen the best response.0ok this is the part that confuses me this division. My book here makes it so confusing

Best ResponseYou've already chosen the best response.0like where do you get all of those numbers from? Sorry I just don't get this at all.

Best ResponseYou've already chosen the best response.2So you need help with synthetic division?

Best ResponseYou've already chosen the best response.2Do you understand the part about the possible rational roots?

Best ResponseYou've already chosen the best response.0I actually think I figured out what you did to get those numbers now so nvm on that ? I understand the possible rational roots

Best ResponseYou've already chosen the best response.2So you need help with the synthetic division process?

Best ResponseYou've already chosen the best response.0do i have to do the synthetic division for every possible rational root?

Best ResponseYou've already chosen the best response.2No. Just until you find one where the remainder is 0. That indicates that you have found a factor. Then you can start working on the quotient to find more roots.

Best ResponseYou've already chosen the best response.0so it is a rootif it comes out equaling zero. ok so now that im following you we can keep going sorry about that

Best ResponseYou've already chosen the best response.2So since the second factor is a quadratic and it won't factor, we just plug it into the formula to find the roots.

Best ResponseYou've already chosen the best response.2Do you have another problem? Perhaps if we start another one from scratch, it will help you understand. I can guide you.

Best ResponseYou've already chosen the best response.2It is so hard to help someone who won't respond.

Best ResponseYou've already chosen the best response.0It's alright. I think I got it figured out. Feel bad I left him hanging there darn computer for some reason it doesn't ever like this site
