By multiplying the whole thing by 1/3, do you mean multiplying the (x + 1/3) by 3 and multiplying (3x2 - 6x - 6) by 1/3 ?
I'm not sure what I did wrong, but maybe I messed up the quadratic formula..? I tried to use the quadratic formula on (3x2 - 6x - 6) and ended up with x = 3 +/- sqrt(15) instead of 2 +/- sqrt(3) for
Ohhh I figured out where I went wrong. And I guess that applies to the bit about multiplying the whole thing too. I completely forgot that quadratic formulas needed to have the equation be simplified. Woops o_o.
Thanks for the explanations!
EDIT: Uh, quadratic equations don't need equations to be simplified right? I think I just messed that part up (forgot to multiply the bottom of the fraction by 3 as part of 2a --> 2(3))
