Question 470833
{{{x^2-5x=9}}}
{{{x^2-5x-9=0}}}
 {{{x = (-b +- sqrt( b^2-4*a*c ))/(2*a) }}} 
{{{a=1}}}, {{{b=-5}}}, {{{c=-9}}}
 {{{x = (-(-5) +- sqrt( (-5)^2-4*1*(-9) ))/(2*1) }}} 
 {{{x = (5 +- sqrt( 61))/2 }}}
 {{{x1 = (5 + sqrt( 61))/2=6.41 }}}  
 {{{x2 = (5 - sqrt( 61))/2=-1.41 }}} 
Answer: {{{(5 - sqrt( 61))/2}}}, {{{(5 + sqrt( 61))/2}}}
