Question 83687
{{{x = (-b +- sqrt( b^2-4*a*c ))/(2*a) }}}
{{{ 3x^2 = 11x + 4}}}
{{{-3x^2 + 11x + 4 = 0}}}
a = -3
b = 11
c = 4
{{{x = (-11 +- sqrt(11^2-4*(-3)*4 ))/(2*(-3)) }}}
{{{x = (-11 +- sqrt(169))/-6 }}}
{{{x = (-11 + 13) / -6}}}
{{{x = (-11 - 13) / -6}}}
{{{x = -(1/3)}}}
{{{x = 4}}}
I got the same numbers with opposite signs from your answers
