Found this on a test for an integrated algebra 2 high school math class! Factor completely. 6x3 - 3x2 + 12 3. The attempt at a solution 3( 2x3 - x2 + 4) eq.1 At this point I checked for rational roots using the rational roots theorem and synthetically dividing. I got nothing. Although this doesn't get us anywhere x2 can be factored out of the first two terms: 3[ x2(2x-1) +4)] eq. 2 I then plugged this guy into Wolfram and it is giving me 1 nasty irrational and 2 nasty complex roots. I'm convinced this is NOT "nicely" factorable. Does anyone have any insights?
