3x^2 + 6x +3 =0
first divide each term by 3, the fact that the right side is zero and zero divided by anything is zero, we can just drop the 3
x^2 + 2x + 1 = 0
(x+1)^2 =
take √ of both sides
x+1 = 0
x = -1
You had it factored correctly, but you "lost " your equation by dropping the =0 part.
Oh, thanks a lot!
