x^2+6x+9
..
you should quickly notice that this is a perfect square. Remember the rule for a perfect square: take half of the coefficient of the x-term and square it to get the third term. You can see that the given equation is a perfect square and will factor to (x+3)^2
solving for x,
(x+3)(x+3)=0
x=-3 (multiplicity of 2)
