Question 935231

Up to my last question and I'm stuck:

Consider the equation 3x2 - 2x - 1 = 0.  (*note - the first part 3x should show as 3x and the 2 sitting higher than the x - not sure how to do this on my keyboard) The sum of the roots of this equation is:

1
2
-1/3
2/3
none of the above

Thanks!
<pre>
{{{3x^2 - 2x - 1 = 0}}}
Sum of roots = {{{- b/a}}}, with a being 3, and b being - 2
This results in: {{{- (- 2)/3}}}, or {{{highlight_green(2/3)}}}
