a. $1\pm \sqrt{3}$ b. ${-2,2}$ c. $1\pm \sqrt{5}$

you can either complete the square and then solve or use the general quadratic formula... the equation doesn't factor

I'd rather complete the square first so I think I would start by adding four to both sides and then adding one to both sides but I'm not sure about that

Never mind I was able to figure out it was c thanks for the help anyway though.
