Best ResponseYou've already chosen the best response.1From my calculations, it's unfactorable. Is this a multiple choice answer?

Best ResponseYou've already chosen the best response.0It's not multiply choice. It is factorable, but into two quadratics. Those cannot be factor. All I'm asking is how do you factor this?

Best ResponseYou've already chosen the best response.0is 1 , 2 , 4,5,10, 20 also factors of 20 ?

Best ResponseYou've already chosen the best response.0so , now one by one put : \(\pm 1,\pm 2, \pm 4, \pm 5, \pm 10, \pm 20\) at the place of x in the given expression

Best ResponseYou've already chosen the best response.03x⁴17x³12x²62 x+20 for example : \(3(1)^4 17(1)^3 12(1)^2 62(1)+20\) \(3 +17 12 + 62 + 20 \) \(84 \ne 0\) Do like this for each : \(\pm 1,\pm 2, \pm 4, \pm 5, \pm 10, \pm 20\)

Best ResponseYou've already chosen the best response.0You know what? Save your time and help someone else. I'm googling Factor theorem. Thanks, though.

Best ResponseYou've already chosen the best response.0if the lowest terms with integer coefficients are quadratics, there aren't any.

Best ResponseYou've already chosen the best response.0\(\large 3x^417x^312x^262x+20 =(3x^2+4x+10)(x^27x+2)\) "Link would be helpful too. " I read a post about factoring into quadratics. Here is a post in which someone tried to explain the method of factoring into quadratics, but I could not understand it. :( http://openstudy.com/users/dpainc#/updates/4fcfdafce4b0c6963adaf2bc

Best ResponseYou've already chosen the best response.0I don't think that that would apply in this situation, unless you could see that x^2 7x + 2 is a factor.
