Question 421527
Solve: First substitute {{{x^2=y}}} and the equation written:


   {{{6y^2-7y+2=0}}} Use the quadratic formula to solve this equation.

   {{{ y= (-(-7)+- sqrt((-7)^2-4(6)(2)))/2(6)}}}

    {y=1/2, y=2/3}

   {{{ x^2=1/2}}}, {{{x=+-sqrt(1/2)}}}

   {{{x^2=2/3}}}, {{{x=+-sqrt(2/3)}}}

      {{{-sqrt(2/3)}}},{{{+sqrt(2/3)}}},{{{-sqrt(1/2)}}},{{{+sqrt(1/2)}}}
