<PRE><B>Question 169895</B>
Please help show me how to work this problem out..Thank you... 
solve equation using the quadratic formula 
1/3x^2 + 2/9x - 1 = 0
------------------
{{{1/3x^2 + 2/9x - 1 = 0}}}
Multiply by 9
{{{3x^2 + 2x - 9 = 0}}}
**[invoke solve_quadratic_equation 3,2,-9]
The solver gets it wrong when the coeff of the x^2 is not 1, so ignore the factors.
---------------
It&#39;s (-1 + sqrt(7))/3 and
(-1 - sqrt(7))/3
