Question 852225
{{{(x^2+8x)/3=-7/9}}}
{{{3(x^2+8x)=-7}}}
{{{3x^2+24x+7=0}}}
{{{x = (-b +- sqrt( b^2-4*a*c ))/(2*a) }}} 
{{{x = (-24 +- sqrt( 24^2-4*3*7 ))/(2*3) }}} 
{{{x = (-24 +- sqrt(576-84 ))/(6) }}}
{{{x = (-24 +- sqrt( 492 ))/(6) }}}
{{{x = (-24 +- 2*sqrt( 123 ))/(6) }}}
{{{x = (-12 +- sqrt( 123 ))/(3) }}}
