Question 103590
{{{(x + 2)^2 = 7}}} 
{{{sqrt((x + 2)^2)}}}= + or - {{{sqrt(7)}}} Take the square root of both sides.
1.{{{x+2=sqrt(7)}}} Positive square root of the right hand side.
2.{{{x+2=-sqrt(7)}}}Negative square root of the right hand side.
Two solutions : 
{{{x=sqrt(7)-2}}} 
{{{x=-sqrt(7)-2}}}
