## anonymous 5 years ago 8k^2-19k+9 is this a prime polynomial???

It does not have integer roots. $(-b \pm \sqrt{b ^{2}-4ac})/2a$ Which I believe gives you $(19\pm \sqrt{73})/16$

no tsuppose to use the qudratic equation

3. anonymous

Actually, I'm wrong, sorry. The factorization is (9x-3)(2x-3)

Aw crap - I did it again. That's incorrect too.

i just wrote it down as being prime
