Question 196373
{{{2x^2 - 3x + 1=0}}}
{{{x = (-b +- sqrt( b^2-4*a*c ))/(2*a) }}}
{{{a = 2}}}
{{{b = -3}}}
{{{c = 1}}}
{{{x = (-(-3) +- sqrt( (-3)^2-4*2*1 ))/(2*2) }}}
{{{x = ( 3 +- sqrt( 9 - 8 ))/ 4 }}}
{{{x = ( 3 +- 1)/ 4 }}}
{{{x = 1}}}
{{{x = 1/2}}}
If you plug these values into equation,
they both check OK
