Subtract 8 from both sides. List the possible rational roots and use synthetic division.

what is synthetic division?

still confused as to what that was.... please reexplain. I don't understand the image.

Perhaps you have never studied synthetic division. What class are you taking?

divide that polynomial by (x2)

I will tell you why I told you to divide by x2

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

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

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

Check your work Azteck. 2 is NOT a root

hey.. guys?! I'm still really confused as to how I'm supposed to solve this...

There is one real root of approximately 2.2 and 2 complex roots. That's from Wolfram

So perhaps you could solve it with a graphing calculator.

um... I still don't understand how to find x myself... without wolframalpha...

You 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.

But I have to solve it algebraically

Sorry. I can't help you with that. Better page Satellite73

could you shoot him a message for me, I've not come accross him so I can't contact him.

He will get to you now.

shoot. He doesn't accept messages from anyone he hasn't fanned :(

This is quite difficult without software lol. Did you see the EXACT forms of the solution... one mega expression!!
 one year ago

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