do you have to complete the square here?
Yes! So far I have moved the constant to the LHS and have factored out the 2. I don't know where to go from there.
don't factor out the 2 you have an equation, divide by 2

Other answers:

\[2x^2 + 4x + 1 = 0\\2x^2 + 4x =-1\\ x^2+2x=-\frac{1}{2}\]
then complete mr square half of 2 is 1, and 1 squared is 1 go to \[(x+1)^2=-\frac{1}{2}+1\]
Ah, I see now. Okay, so from there I would have (x + 1)^2 = 1/2 and then x = -1 + or - radical 1/2
yes
Thank you! This helped a lot. Do you think that you can help me with one more problem? At least half way?
