Question 919392
{{{x^2+6x-5=0}}}


{{{x = (-6 +- sqrt( 6^2-4*1*(-5) ))/(2*1) }}} 


{{{x = (-6 +- sqrt( 36+20 ))/2 }}}


{{{x = (-6 +- sqrt( 56 ))/2 }}} 

{{{x = (-6 +- sqrt(4*14 ))/2 }}}

{{{x = (-6 +- 2sqrt(14 ))/2 }}}

{{{x = (-6 +- 2*3.74)/2 }}}

{{{x = (-6 +- 7.48)/2 }}}

solutions:

{{{x = (-6 + 7.48)/2 }}}

{{{x = 1.48/2 }}}

{{{x = 0.74 }}}

or

{{{x = (-6 -7.48)/2 }}}

{{{x = -13.48/2 }}}

{{{x =-6.74 }}}
