Question 324867
{{{x^2+8x-2=0}}}
{{{(x^2+8x+16)-2=16}}}
{{{(x+4)^2=18}}}
{{{x+4=0 +- 3sqrt(2)}}}
{{{x=-4 +- 3sqrt(2)}}}
.

.
{{{x = (-b +- sqrt( b^2-4*a*c ))/(2*a) }}}
{{{x = (-8 +- sqrt( 8^2-4*1*(-2) ))/(2*1) }}}
{{{x = (-8 +- sqrt( 64+8))/2 }}}
{{{x = (-8 +- sqrt( 72))/2 }}}
{{{x = (-8 +- 6sqrt( 2))/2 }}}
{{{x = -4 +- 3sqrt( 2) }}}
