Solving 2r² + 2r + 1 = 0

[Punchlinegirl]

I'm feeling really stupid right now, but I can't seem to get this to factor.
2r^2 +2r+1= 0
Can someone please help me out?

You could factor it if you knew its roots, right?

 

[Punchlinegirl]

so to find the roots I'd use the quadratic formula
-2 +/- $$\sqrt 4-8$$ /4
so then would my roots be -.5 +/- 2i?

I think you divided wrong. But you have the right idea. (And you should use parentheses when appropriate)
