Find the roots of the function

f(x)= x^2 +2x+2

a)-1 + sq root of 2 and -1 - sq root of 2

b) -1 + i and -1 - i

c)-1 -2i sq root of 2 and -1-2i sq root of 2

d)-1 +2i and -1-2i

The i's are in italics but I can't .make them in italic here for some reason

completing the square:

x^2+2x +1= -2 +1

(x+1)^2=-1

x+1= +-** i** sqrt2

solve for x
