Question 677334
{{{x = (-b+-sqrt(b^2-4ac))/(2a)}}}


{{{x = (-(-2)+-sqrt((-2)^2-4(1)(-8)))/(2(1))}}}


{{{x = (2+-sqrt(4-(-32)))/(2)}}}


{{{x = (2+-sqrt(4+32))/(2)}}}


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


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


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


{{{x = 8/2}}} or {{{x = -4/2}}}


{{{x = 4}}}    or    {{{x = -2}}}
