Question 108755
Solve by completing the square:
{{{x^2 + 6x +1 = 0}}}
{{{x^2+6x+____ = -1}}}
{{{x^2+6x+(6/2)^2=-1+(6/2)^2}}}
{{{x^2+6x+9=-1+9 =8}}}
{{{(x+3)^2=8}}}
{{{sqrt(x+3)=sqrt(8)}}}
{{{x+3=sqrt(8)}}}
{{{x=-3+-sqrt(8)}}}
{{{x=-3-sqrt(8)}}}
{{{x=-3-2.83}}}
{{{x=-5.83}}}
or;
{{{x=-3+sqrt(8)}}}
{{{x=-3+2.83}}}
{{{x=-.17}}}
