Best ResponseYou've already chosen the best response.0still confused as to what that was.... please reexplain. I don't understand the image.

Best ResponseYou've already chosen the best response.0Perhaps you have never studied synthetic division. What class are you taking?

Best ResponseYou've already chosen the best response.0divide that polynomial by (x2)

Best ResponseYou've already chosen the best response.0I will tell you why I told you to divide by x2

Best ResponseYou've already chosen the best response.0You have to test a number in that polynomial so that x^3x^2+x8=0 is true.

Best ResponseYou've already chosen the best response.0It won't do any good to divide by x2 since x2 is not a factor.

Best ResponseYou've already chosen the best response.0if you substitute 2 for x then you get 0=0 which means 2 is a root of that polynomial.

Best ResponseYou've already chosen the best response.0Check your work Azteck. 2 is NOT a root

Best ResponseYou've already chosen the best response.0hey.. guys?! I'm still really confused as to how I'm supposed to solve this...

Best ResponseYou've already chosen the best response.0There is one real root of approximately 2.2 and 2 complex roots. That's from Wolfram

Best ResponseYou've already chosen the best response.0um... I still don't understand how to find x myself... without wolframalpha...

Best ResponseYou've already chosen the best response.0You could graph it. You could substitute values until the function changes signs and then zero in on the answer by making and checking successive guesses.

Best ResponseYou've already chosen the best response.0This is quite difficult without software lol. Did you see the EXACT forms of the solution... one mega expression!!

Best ResponseYou've already chosen the best response.0the real root, for example, is this: 1/3*(12 (2/(209+3 sqrt(4857)))^(1/3)+(1/2 (209+3 sqrt(4857)))^(1/3))
