From my calculations, it's unfactorable. Is this a multiple choice answer?

It'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?

How do you factor 3x⁴17x³12x²62 x+20 into two quadratics?

I get it. I know I have a video of this somewhere. One second.

Factor theorem will surely work.

is 1 , 2 , 4,5,10, 20 also factors of 20 ?

so , 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

In which you get the answer as 0 ?

3x⁴17x³12x²62 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 : \(\pm 1,\pm 2, \pm 4, \pm 5, \pm 10, \pm 20\)

those are only the rational roots

we want integral roots...

You know what? Save your time and help someone else. I'm googling Factor theorem. Thanks, though.

if the lowest terms with integer coefficients are quadratics, there aren't any.

MrMoose Group TitleBest ResponseYou've already chosen the best response.0
factors, not terms

\(\large 3x^417x^312x^262x+20 =(3x^2+4x+10)(x^27x+2)\) "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

I don't think that that would apply in this situation, unless you could see that x^2 7x + 2 is a factor.
