Question 926702
{{{ 9x^3+25x =30x^2}}}
move {{{ 30 x^2}}} to the right
     {{{ 9x^3-30x^2+25x=0}}}
      {{{ x(9x^2-30x+25) =0}}} 
         possible solutions:
 Either x=0 or {{{(9x^2-30x+25) =0}}}
 one solution is 0
we need to find out other solutions
 so  {{{(9x^2-30x+25) =0}}}
     *[invoke quadratic "x", 9, -30, 25 ]
 So Solution  = 0 ,  1.667,1.667
